When I was a child and reading SciFi fiction, I came to the conclusion that WE are energy parts of a god/universe. I believed that when we die, our energy (or souls to some) join that energy. We meld with the entity behind the universe and become part of it with or without conscience. Not so sure now, but I'll keep that theory open. Be cool to have a conscience entity that joins him.
Still, when we die and not aware we died, so what? If it's the end of conscience so be it. We won't know.
Since you threw this out there, (not finding right words) done in honesty and politeness, then an honest and polite reply will be made in return:
It is my - and many others - understanding that God wants us to worship him, but it is NOT because he needs worship. God doesn't need anything we can provide him - you're right, that would be petty, and hence that isn't something that God could possibly be.
However, He certainly wants us to worship Him - with good reason. By worshipping Him:
a) We become AWARE of the messages He has sent us through His prophets, His Son that was made incarnate on this earth, and in the case of the 10 Commandments, what He actually took the time to scribble out on to stone tablets; and
b) We are inclined to actually FOLLOW those instructions, out of both love, and/or, as hell exists, out of fear.
Hence, by worshipping God, we become what God wants us to be.
I believe the creator, which I believe in, behind the "singularity" did it for reasons that will never be known.
BINGO! I completely agree. So does God, as He stated as much to Job in the Bible's Book of Job!
CS. Lewis once said that god created the universe because he was lonely. Threw out a bunch on the big bang to see what could happen, while hoping something more would come of the gases, galazies, plantary systems.
As someone who does engineering using the very edges of the nature of matter and energy, including quantum effects, I am convinced that nothing God did was out of hope - it was out of purpose.
Something else to remember - it appears time itself is just a flexible aspect of space-time. When God created the singularity (?) that set this universe in motion, He did it in a context that is outside of time, or at least time as we know it.
This means it is quite probable that even by the laws of physics as we know them, that Creator already has complete insight into the conclusion (as we would perceive it, being entities that have to live in the space-time continuum) of all the processes that were unleashed in the Creation.
When viewed in that context, concepts like "hope" and "loneliness" take on a different flavor. Who knows what the true purpose and plan of God - He's Him, and we're just His creation. However, I suspect that "neediness" is not a concept that applies to Him.
