There's reasonably compelling evidence that the nucleobases that form our DNA (adenine, guanine, cytosine, thymine) have extraterrestrial origins. We may only be here because meteorites carrying the building blocks of DNA crashed into Earth millions of years ago.

Yes, that is what I'm referring to. It may very well be happening continually. That would mean that it is a fallacy to draw a line at terrestrialism: a planet's gravital influence means nothing, just like "up" and "down" mean nothing in space. The line would instead have to be drawn in time at pre-complexity and post-complexity, or pre- and post-sentience.

I think this is entirely possible, if not likely.

I used to buy and sell meteorites on eBay. I would buy large slices and break them up into gram sized chunks. Repackage the pieces into collections of 15 different sample and sell. I ended up with my own collection of 125 different rocks.

For me the answer depends on whether or not any organism could survive entry into the atmosphere. I think they can. The other factor is can they establish themselves.

I have tasted these rocks. The 1st one was an accident. All others are not. That 1st one is called tattonie/so. Is lime green salty. Made me mildly sick for a few days but I Survived.

I love my collection...
