When i read the name, and the creator, i knew the answer ahead :P
Most of the chances is that they exist, cause there are some many Galaxies, so many planets, so what the hell is the chances for us to be damn alone in this endless universe?
If there is god, why he left us alone in this universe he created, or maybe, he created only this galaxy? And other gods created other galaxies? You can't know the answer now, but you need to think at least, if its logical or not.
