Does this subject confuse you? Well, maybe this won't help more.
Has anyone thought that maybe the Big Bang was caused by an intelligent being, entity, omniscient thing? If one thinks this way, could the Big Bang be called Intelligent Design? Maybe our universe is just a result of some larger universe and some kid in that universe spit up some bad grub and we are the biological, bacterialogical stuff that is mixed with that spitum.
You all do realize that everything is theory and there are no concrete, set in stone, facts, right? Evolution is a theory. I would say God is a theory. Intelligent Design is a theory. The only reason some theories make it is there is evidence that support it.
The bottom line is WE DO NOT KNOW! We will not know until we die. Even then, we may not even know. For all we know death here is birth in another universe. Maybe reincarnation is correct and we come back as some other thing. I guess we just don't like not knowing.
If all this is too much for you, find a copy of God's Debris by Scott Adams. That will make your head spin or actually enlighten you. Fascinating reading.
