It is not upon me to prove no god exist.
You've made the common mistake of conflating the rejection of a position with the positive affirmation of it's opposite. You do have an obligation to prove no deity exists if you claim that no deity exists.
Gods do not exist at this time because the burden that falls on the person making the claim has factually never been substantiated.
What was the tallest mountain on earth before the discovery of Mt. Everest? Mt. Everest.
It is factually not a necessity for me to possess all possible evidence when discounting claims of purple flying unicorns
"Factually" it is necessary for you to account for all possible evidence when claiming that no possible purple flying unicorns exist. Again, you conflate the discounting of a claim with an opposite claim.
I've used this analogy before to help someone struggling in understanding:
I have no knowledge of relative skill among rugby teams and someone tells me that the NZ All Blacks' are the most skilled rugby team around. As he appears to be a big All Blacks' fan, I don't find this convincing and I reject his claim: I do not believe that the All Blacks' are the most skilled rugby team. I have not, however, claimed that the All Blacks' are not the best, that would be unsupported conjecture.
That last line is unfortunately where you are now.
