Any other atheists here? Some frustration

[Thorne]

Assume there is no god (as per assuming the Scientific Method)
Therefore there is no god.

No, the way it actually works is:
1. Assume there are no gods.
2. Do our models and theories about the working of the universe still apply?
3. Yes, they do.
4. Then there probably are no gods.
5. Is there any evidence to show that there are gods?
6. No verifiable evidence at all. Only wishful thinking and anecdotes.
7. Then, to the best of our knowledge, there are no gods.

So aren't actually strong arguments against the existence of god.

We don't need any arguments against the existence of gods, any more than we need arguments against the existence of fairies, or leprechauns, or golems, or any other such superstitious claptrap. The point is that there is no credible evidence that gods exist. It's not up to science to prove that gods don't exist: it's up to believers to prove that they do, in a testable manner.
