Well tell your mate god we can analyse his efforts and wether they are fake after he's provided us with a few
So far ......absolutely nothing
God is omnipotent......your words .......and omnipresent .....your words
If he is then he's doing a crap job of showing us that he is all powerful and everywhere , at all times

The Middle East ......loads of deaths .....mostly to do with him and who he said what to and who's land he gave to who etc
Start with that
Have a mass prayer with all his followers and contact him
Here is his chance
