Spoiler This supports my theory that Megatron is waiting for us on the other side of the moon. Also something about meteorites carrying DNA, which does prove Megatron is waiting.
Megatron has everything to do with everything. Seriously speaking though I'd rather not comment on the specifics of this because I don't want to start a debate. Albeit this is interesting.
Null invoid post! Anyway, on topic. The idea of life from an external source apart from Earth isn't that surprising, I mean a meteorites a giant rock hurtling through space, whilst Earth is a giant rock in a relatively constant orbital state. We all have ot come from some type of rock, whether it's moving or not. Still, at least evidence to the fact is more enlightening then a simple prediction or theory. The hard facts is what science is about.
There is a theory called panspermia... its been around for a while. oh and DNA building blocks have a name. they are called nucleotides.
