That is a very broad question that is impossible to answer for various reasons. God varies based on who you ask and some don't even believe in god. If you ask me, everyone that believes in God have the same God. In my opinion, God is just something people believe in for which they don't know or understand. Whether your God is the creator of all life or aliens or simply a higher being, it is all the same. No one can prove their God exists or explain why or how God exists. I for one believe that there is a higher being somewhere. That doesn't mean I believe in magic. Like God created all life and everything around it? I ask how? This isn't Harry Potter lol. God didn't just snap his fingers and create Adam and Eve. It's pointless arguing with that type as well because their answer is always "if you don't believe then you don't understand" or "you have to have faith and just know God is real" or my fav. "You have to have a relationship with God to truely understand." I am more inclined to believe aliens exist. I mean earth is nothing in the scheme of things. We can't even comprehend how big the universe is and all the planets that exist. It would be dumb to believe we are the only intelligent life forms in the whole universe. People often refer to the bible as proof that god exists. To me, the bible is a book, written by man. It has been passed through the ages and surely has been changed as time has gone on so who is tp say the bible as we know it today is even the original bible? How do we know it isn't one of the first "stories" passed on that people misinterpreted as being real? How do we know it wasn't the first law book someone created to control the people? What I often tell people is if I was around during those times and happened to write a book that got passed on through the generations, how do we know it wouldn't be worshipped today?
