Actually, science has gone quite a long way in explaining it. The start of time as we knw it, is the big bang. This will probably be simple enough for you:
http://www.big-bang-theory.com/As for simplicity. I think you will find it goes.
Benevolent, omnipotent creator.
Creator
Creation
Declaring that the universe is 'created' by something which you seek to personify just makes things even more complicated. Questions arise such as who created the creator? Why did the creator create etc..etc.. And you cannot escape these questions. You have already said youself that something cannot just come into existence without cause, so you ahve to explain how the creator did. So you can see how this explanation is so much more complicated than the simple creation explanation.
Oh like christianity? A religion which tells africans condoms are evil, which in turn helps to spread one of the most deadly and indiscriminate viruses around Africa, or maybe we can discusss the vast cabal of child rapists and abusers which have been exposed to exist withing the highest echelons of the faith, despite it's attempts to protect them. Maybe we can focus on christianities war of genocide against the Muslims in Bosnia and the former Yugoslavia? The horrors of christian misssionary around the world, the inquisition and so on and so forth.
Or maybe Judaism? A religion which along with it's Islamic cousin is threatening WW3 in the west bank and Jerusalem. Where it's adherrents want to knock down someones holy building to build their own holy building because God told them to?
Or amybe their evangelical supporters who only do so, because they think that they are hastening the apocalypse? Hence the prophecy, when all the Jews are dead or enslaved the messiah will return and bring about the reckoning etc..etc..
People actually really believe these things and will stop at nothing to make them happen.
And that is just two thirds of the abrahamic faith. You said above you aren't defending Islam, so i didn't list the horrors which eminate from that faith. but i could if you want me to? I don't see how it would help your argument though?
I have said it before i will say it again. Assertions made with no evidence can be dismissed in the same way.
I wonder, would all those thousands of priests and bishops have been child rapists if they werent forced to become virgins?
Would the pope have indirectly killed millions if he hadn't been a chrisitan Would he still have spread the word around Africa that condoms are evil? Would he still have condemned millions of children to die needlesly of aids?
LOL Socialism was a religion in itself. Centered around an all powerfull leader, whos name could not be taken in vain, and around whom was created a cult, much the same as that which exists around religious leaders or profits. We could look at North Korea now, where the glorioous leader was said to be born of a virgin, and that when he was born, all of the birds began singing in Korean. If that is your idea of a secular and non religious society then i suggest you do some reading.
What book! You keep talking about 'the book' what book is this?
I live my life by rules and morals such as you should not kill. And that is final. You live your life by rules and morals such as thou shalt not kill...unless god tellls you to.
