Oxygen is measurable. We can detect even tiny amounts of it, we know its makeup, we have well characterized its behavior, and we can make it work for us.
We have no evidence for the existence of any gods. Seems like we can exist without them just fine.
wb the Quran? The only book uncorrupted in its existence. In it God says He will preserve the book, and if it is a fabrication He challenges you to produce even a single Suraht (chapter) like it. Also neither God nor the angels will appear until the Day of Judgement, so asking for either while you persist in disbelief is kind of a bad idea.

First of all, even if we take what you're saying at face value, how does it being an original text in any way prove that its contents are true? If I made up a completely original story today about a stuffed animal that eats pickles and poops diamonds, would that mean that such a thing exists?
Secondly, we can't take what you're said at face value because Qur'anic and Muslim scholars are very divided about the origins of the Quran.
