Is atheism a scientific perspective?

[robvalue]

Can life exist that wasn't designed by another life form?

Yes: Fine. Let's keep searching for answers to abiogenesis, and consider all new evidence as it comes in regarding our origins. No need to jump to conclusions about "design".

No: You have to accept an infinite regression of "designers".

Of course, we all know you're talking about "God" and not just some generic designer, and that you'll use special pleading to remove the rules from him that you demand are placed on everything else.

Life evolves all the time without design. New species emerge, without our intervention. If we're not talking about new species, then we're merely talking about abiogenesis, which is nothing to do with evolution. So all the "problems" with the ToE become irrelevant. Again, I have no idea where these guys think the design stage was, further than the initial design of our reality that they already assume. A dude who sets things in motion (billions of years ago) is consistent with what we observe (although not necessary). A dude who keeps coming down from somewhere to "design" new life forms by magic or something is not.
