Is atheism a scientific perspective?

[Mister Agenda]

So we have what humans make, which is a product of intelligent design. And we have some other things, not made by humans, which have some similarities to things humans make. And the argument boils down to 'if things humans make are the product of intelligent design, these other things MUST also be a product of intelligent design.'

Without knowing anything at all about the 'other things' being talked about, we've got a hasty generalization fallacy.
