That's only true in your head and nowhere else.
So the entire scientific community is engaged in a massive conspiracy against intelligent design according to you and the scientists are willingly living in the dark ages.
Cooperton: Pakicetus was even admitted to fully be a land animal in the paper published in nature. Hardly a transitional fossil into a whale.
What nonsense for once more.
You are in the very dangerous path of total denialism of reality.

No that's literally a video of people that are outside of my head. You thinking that EVERY scientist believes in evolution is exposing your dogmatic view of this whole thing.

We have been teaching it to kids for multiple generations now. It is indoctrinated in people. How does any false belief reach popularity? Look at how you all are treating someone who is challenging evolutionary theory... they do the same in the professional setting as well. People get fired for challenging evolution.

It's a direct quote from the paper, even the researchers themselves concluded that this creature was not amphibious:
"pakicetids were terrestrial mammals, no more amphibious than a tapir."
Nature, 2001
The first whales appeared 50 million years ago, well after the extinction of the dinosaurs, but well before the appearance of the first humans. Their ancestor is most likely an ancient artiodactyl, i.e. a four-legged, even-toed hoofed (ungulate) land mammal, adapted for running. Cetaceans thus have a common ancestor with modern-day artiodactyls such as the cow, the pig, the camel, the giraffe and the hippopotamus
The grey wolf (Canis lupus) was the first species to give rise to a domestic population, and they remained widespread throughout the last Ice Age when many other large mammal species went extinct. Little is known, however, about the history and possible extinction of past wolf populations or when and where the wolf progenitors of the present-day dog lineage (Canis familiaris) lived1,2,3,4,5,6,7,8. Here we analysed 72 ancient wolf genomes spanning the last 100,000 years from Europe, Siberia and North America. We found that wolf populations were highly connected throughout the Late Pleistocene, with levels of differentiation an order of magnitude lower than they are today. This population connectivity allowed us to detect natural selection across the time series, including rapid fixation of mutations in the gene IFT88 40,000–30,000 years ago. We show that dogs are overall more closely related to ancient wolves from eastern Eurasia than to those from western Eurasia, suggesting a domestication process in the east. However, we also found that dogs in the Near East and Africa derive up to half of their ancestry from a distinct population related to modern southwest Eurasian wolves, reflecting either an independent domestication process or admixture from local wolves. None of the analysed ancient wolf genomes is a direct match for either of these dog ancestries, meaning that the exact progenitor populations remain to be located.

What does creationism say about the evolution of wolves?
Let me guess!
If wolves evolved at some stage and some of them became domesticated dogs then why don't wolves evolved today to become dogs. I think I get you!
New research shows how octopuses may have evolved
new paper in Genome Biology and Evolution indicates that a type of octopus appears to have evolved independently to develop something resembling a shell, despite having lost the genetic code that produced actual shells in its ancestors and relatives.
Argonauta argo is a species of octopus that lives in tropical and subtropical open seas. Female argonauts have a protective, spiral, shell-like egg case, which protects the eggs inside. Researchers have long wondered about the origin of this egg case. It looks very much like the shell of the commonly known pearly nautilus (the very distant relative of the argonaut), which has a true hard shell and lives on the ocean floor, but that may just be a coincidence.

Now do Octopi.

Okay.
Octopi are cephalopods.
The first cephalopods arose as nautiloids in the Cambrian.
Here is the early cephalopod:
In the current tree of life
Nautilus is to Octopus as squirrel is to Human, still both cephalopods and mammals respectively, but the former of each is FAR closer to the primative varieties in the taxonomic classes.
It's a fallacy that creationists use. "Why are there still animals in all stages of supposed evolution?"
Like because a modern nautilus (in the cephalopod class) is still closer to a Cambrian nautilus it means there weren't other niches for some variations of cephalopod to exploit.
But alas, some Nautiloids branched off. Some cephalopods straightened out their shells, and by the Ordovician (440 MYA), some nautiloids had taken up this configuration:
Which led to losing the shell by 160 million years ago, eventually becoming modern squid and octopi.
The reaction kinetics can be influenced by factors such as the activation energy required for the reaction to occur and any competing side reactions. Additionally, in a biological context, enzymes often catalyze the formation of peptide bonds, lowering the activation energy and accelerating the reaction rate, making it more biologically relevant.
We hypothesize that atmospheric aerosols may have played a major role in the prebiotic formation of peptide bonds by providing the thermodynamic driving force to facilitate increasingly stable linear oligopeptides. In addition, we hypothesize that small aerosols orient amino acids on their surfaces, thus providing the correct molecular orientations to funnel the reaction pathways of peptides through transition states that lead eventually to polypeptide products.
Funny you'd bring up dark matter, everything is dark until we understand it's true mechanism interacting with our physical world
Oh and the speed of light is only a theoretical limit that needs to be applied for an explanation that builds on the observable only.
It's the limit of our processing speed, but is there really nothing faster?
It's religion that has created a God according to the anthropomorphic principle and the beliefs of old men in the middle east. Don't forget God is a male character and quite unpleasant if you don't believe in him.
A magical invisble being created everything or intelligent beings created life, with both leaving the question 'who created them then?' The simplest hypothesis is life is basically just part of the evolution of the universe, where the conditions are just right, life will evolve.
So to posit "interdimensional", you are absolutely positing a plane of worlds with different universal histories.
So we are in string theory territory.
And string theory has an interesting answer for universal laws. Infinity of infinity is implied up around 8, 9, and 10.
So this insignificant universe has life, and everything the way it does, because it has to. Every variation in every conceivable way exists and HAS TO. Hence, EVERY specifically 'designed' universe is merely a requirement of the theory.
If you really think about it, that circumvents intelligence being necessary. Because IT HAS to happen. That, or intelligence is an interchangeable term for infinity. God is LITERALLY EVERYTHING in every conceivable way.

I was in the NASA Facebook group yesterday and this subject came up.
When I tried to post the following it was immediately declined by their group bot:
"Dark Matter + Dark Energy = we have no clue at all about this."
No matter how I phrased it, it was "declined" and not posted.
I even tried posting a message to the groups admins asking if their bot had bumped it's head or something. And guess what the response was?
"Declined".
You can't make this stuff up.
NASA is the biggest Luddite out there.
What are they afraid of?
