God is God when dealing with the absolute. The God of the cosmos or existence, what ever word you want to use in this day and time is the same being. God is all knowing, all powerful, and all pervading. Therefore by useing logic, God is God on any planet, star, in any galaxy, alternate reality, or what ever else.
The individual being is very limited compared to God so we can only see and experieince with limited senses. It is not a matter of being right or wrong in my eyes, it is a matter of experience, perception, and blessings. Those that worship God by differnt names experience God differntly.
Just like there are somany forms of education, yet people eperience them differenlty. I find that people get passionate about the issue because they have so much fear about being wrong that they project it on others and hope to have strength in number to support their belief.
Oh, the God I serve allows for reincarnation so I am safe all the time. I get it right I make it back to Godhead, I get it wrong I have to reincarnate in some other form in some other world. Makes no difference to me. Some days I kind of want to make it to a world where I am a dragon so I could have some fun.
God does not need us to know he/she/it exist God just exists.
