Scientists have discovered evidence that supports the theory that part of our DNA actually comes from deep space.
People have been discovering components of DNA in meteorites since the 1960's, but researchers were unsure whether they were really created in space or if instead they came from contamination by terrestrial life. For the first time, we have three lines of evidence that together give us confidence these DNA building blocks actually were created in space.
According to the research, the discovery "gives support to the theory that a "kit" of ready-made parts created in space and delivered to Earth by meteorite and comet impacts assisted the origin of life." The obvious implication of this discovery is that, if life blocks are spread through the universe through comets and asteroids that impact on planets, the possibilities of life that uses the same blocks on other planets is a very real one.
"In fact, there seems to be a 'goldilocks' class of meteorite, the so-called CM2 meteorites, where conditions are just right to make more of these molecules," adds Callahan.
Thank you, I was trying to remember the name of the theory. The Wikipedia page suggests that these chemicals are generated via collisions with planets that contain life. It could mean that life on Earth was the result of life on another planet contaminating Earth. However these NASA scientists seem to think the chemicals are actually generated inside the meteorites. There could even be another explanation.

Panspermia (Greek: πανσπερμία from πᾶς/πᾶν (pas/pan) "all" and σπέρμα (sperma) "seed") is the hypothesis that life exists throughout the Universe, distributed by meteoroids, asteroids and planetoids.[1][2]
Panspermia proposes that life that can survive the effects of space, such as extremophile bacteria, become trapped in debris that is ejected into space after collisions between planets that harbor life and Small Solar System Bodies (SSSB). Bacteria may travel dormant for an extended amount of time before colliding randomly with other planets or intermingling with protoplanetary disks. If met with ideal conditions on a new planets' surfaces, the bacteria become active and the process of evolution begins. Panspermia is not meant to address how life began, just the method that may cause its sustenance.[3]

Seems like we are getting closer to disclosure on both ET's and our true origins. The question is, how long till it gets here? Or will ET's land and make the announcement themselves?
not surprising least to me, I already had some idea that we were a hybrid breed. SnF good find

6:1 When man began to multiply on the face of the land and daughters were born to them, 2 the sons of God saw that the daughters of man were attractive. And they took as their wives any they chose. ... when the sons of God came in to the daughters of man and they bore children to them. These were the mighty men who were of old, the men of renown
There is as yet no evidence to support or contradict panspermia, although the majority view holds that panspermia – especially in its interstellar form – is unlikely given the challenges of survival and transport in space.
---
The mechanisms proposed for interstellar panspermia are hypothetical and currently unproven.

Until a large portion of the galaxy is surveyed for signs of life or contact is made with hypothetical extraterrestrial civilizations, the panspermia hypothesis in its fullest meaning will remain difficult to test.
