Would you be an atheist if science and reason wasn't supportive of atheism?

[Zen Badger]

It doesn't "support" the idea of a God. It simply makes the idea of the universe coming about without a God terribly implausible verging on impossible.

Therefore allowing for a rational basis to conclude that it's much more likely that a God exists.

This argument is not easy to refute, but I have some possible answers to it.

This is what is known as a "hypothesis".

When you actually have some evidence to back it up it will be a "theory".
