Have humans ever made aliens by artificially creating life in a lab environment that simulates the conditions on earth when life first started ?

Nothing living but yes these experiments have been done to varying degrees of success. Again, nothing living, but large organic molecules have been produced. I believe someone may have been able to synthesize RNA under early earth conditions as well but i may have misheard that

so it's just up to luck then for life to form

>>12742179
kinda
those experiments also produced amino acids. At that point all it takes is for a piece of rna to somehow make more of itself which isn't all that unlikely if you have a large enough pool. From that point everything else leading up to us is fairly trivial.

If it's from a lab on earth then it isn't an alien then is it.

If it's from a mexican lab then it is.

How viable is it to simulate everythig virtually to speed up (and cheapen) the process for long periods of time?

>> No.12744956

>>12742160
theyve made anaerobic bacteria which is fairly alien, but do exist naturally

Good enough.
Probably the first life was a self-replicating protein, that evolved an RNA to be where it stores the blueprints of how to reproduce those proteins. Then, the RNA evolved self-replication.
RNA eventually became dominant. The same process happened with DNA.

This process is called the Revolutionary Phenotype. It's more detailed than that, but the book covers it.
