main reason for peoples believe in a creator is surely not that someone is needed to create the universe(start the show)-this is not the real reason,this is just an excuse.
Main reason people believe in a creator is fear.Fear from the unknown.And fear from the end of the own ego.
As long as there is a creator there is still a chance to continue,to keep on living in another place,dimension,paradise.
Only few people really cared about how the universe was created,or why.
Few more really care about meaning of life.
But most are afraid to die,because they know this will happen anyway.
That's why "man created god"(that's the reason why god is supposed to have all the characteristisc powerhungry man wishes to have)-a god who will keep you alife after the reapers job is done.
1)noone can be all power full.impossible
Can god create a being that is more powerful than he is?
He can=he is not all powerfull,because he has less than 50% of all power to be able to create a more powerfull being
he can't=he is not allpowerfull because he does not have the power to create such a being
another problem:god allpowerfull(100%)=no devil possible(0% power)
more important is:if god is allpowerfull(100%)=0 %power for his creation=human being has no own will=not responsible for own mistakes=no possibility to change
2)all knowing=no need to create something.as you know everything you simply don't need the universe.
3)of course a creator can be all loving,but there is no need or proof that he/she is so.
4)you are right as long as you don't think that:
all is one and one is all.
5)one creator? pretty logical.
When you start to search the ultimate point of beginning you will realize that something must have been the 1st.
There must be the first living cell(starting point)
just like there was the 1st man on the moon or the mt everest.
Someone must have been the first,no matter how many gods or creators.
6)plan for humanity?
1st there was an evolution of the species(physical)-has happened
awareness maybe the next step:evolution of mind.has also happened(empathy,spirituality,living in harmony with nature and all that stuff)
but right now wrong direction(consume,greed,control,wasting time answering stupid questions in the internet instead of being usefull)
