Is atheism a scientific perspective?

[Chas]

Well, no, it doesn't start with the genome.  It starts with much simpler chemicals and all genomes are products of evolution.

What makes you think that chemicals will produce genomes?

Given elements, energy, and time more complex molecules arise. We see this throughout the universe.

Lone nucleotides or even nucleic acids are not the same as genomes.

No, they are the building blocks. See above.

Similarly, amino acids are not the same as genomes. Not only do you need nucleotide codes to arise, you also need a system to connect this to a protein code to eventually arise as well.

And that system evolved from less complexity.

This information is specified.

By what or whom?

It accomplishes a desired and specific function.

Specific does not mean specified; don't conflate them.

Natural selection is not a shaping force, unless you mean it shaping populations.

Yes, it shapes gene pools by selecting individual organisms for success.

Even then, I would argue that it is a mechanism to prevent genetic degradation by removing the individuals that suffer mutations.

Then you are seeing only half the picture. Or less.
Not all mutations are "suffered". Some are beneficial and lead to greater success thus increasing their presence in the gene pool.

And you said it yourself that mutation and recombination are responsible for the new information. This means that you do in fact assume that the best reproducers are the ones that have deviated from the norm (the mutated ones).

They are the ones that deviated only a little from the norm. You claimed that the ones that deviated the most were selected and that is false.

And we have no idea to what extent mutation/ recombination add information. We don't even know if they can at all.

Of course it can, and does, add information. Any change is information; any change at all.
Have you ever heard of Richard Lenski's work?

Assuming that it can add seemingly infinite information is way too speculative for me.

Try harder.
What would limit it? If small changes accumulate, where is the limit?
