Sure, and so as an atheist and an otherwise “scientific person”, I do accept that god is a valid hypothesis. And I will remain an atheist until any evidence pops up to support that hypothesis.
At some point I think you may have gotten confused by terminology. It is indeed similar to various other scientific ideas, which are believed only after being tested. You do not accept every hypothesis as being the truth until proven otherwise. That is the essential difference between conducting science and exercising one’s imagination.
