I don't know. I sometimes believe and sometimes don't depending on every new discovery they find.
Check out the story of "Red Rain"
Some respected scientists think it's our first -proof- of alien life.
simple cell life.. but still life !
red rain came down it was examined and found to replicate on it's own.
it does not contain DNA and excretes uranium as a waste product.
when the rain happened a meteor had hit the atmosphere in that are and exploded in the sky..
fragments were scanned and contained deep inside it where the same shaped micro organisms.
professional labs and pro scientists tried to get NASA involved but they refused.
It's simple.. if it lives ?
It has DNA.
this red rain contained self replicating living cell's that have no trace of DNA at all !
What do you call that then ?
Watch the show, The Unexplained Files - S01E06 - Alien Rain, Beach Boom & Voynich Manuscript
Which is disappointing.
