I believe there probably are other species of physical beings in this universe, but the likelihood of them visiting us is remote.
Don't ask me why, but I think visits by "extra-dimensional" beings are somehow more likely. And I think that they might use 'found DNA material'
to create bodies for themselves in our physical world.
I have posted about this idea in several threads where it's relevant, but I suppose I should make a thread of my own.
To summarize, I think the "visitors" started this program a long time ago, possibly before man even existed. I think they can 'telekinetically'
alter matter, and 'move things around', and I think they can 'possess' a physical body, but that these activities require massive amounts of
energy and concentration.
But, using those techniques, perhaps they set up a system of farming human fetuses that they somehow mutate into 4 foot tall 'gray' bodies. My
assumption being that an adult human body contains a consciousness that can resist being taken over, therefore being too difficult to possess. A human
child might be easier, but not efficient enough to do the work they need to do. So by accelerating growth or genetically altering the human
body, they can make an 'avatar' or vessel that is strong enough to do work, and also carry the 'alien' consciousness. The big heads are that way
so as to take advantage of the human brain's potential. Think telepathy, telekinesis, other things 'aliens' are said to be capable of.
People talk about a 'hybrid' agenda, but I don't think they're mixing 'alien DNA' with human... I think it's more likely they're tampering
with and mixing the DNA of the fauna and flora they found here.
Which could be a possible explanation for 'reptilians', 'mantis' and even Bigfoot.
I hate this theory and really hope it isn't true, but it does seem to fit. You must admit that 'grays' resemble human fetuses:
When skeptics claim that life elsewhere in the universe would evolve so drastically different from that on Earth, and wouldn't be 'remotely
humanoid' they are probably correct.
