Because you know how houses get built. We know builders exist. There are millions if not billions of examples of houses that were built and you could build one if you so desire.
How do you know the painting had a painter? Because you know how paintings get painted. We know painters exist.
There are millions if not billions of examples of paintings that have been painted and you could paint one if you so desire. How do you know the universe had a creator? You do not know how a universe could be created.
You do not know creators exist. There are no examples of universes that you know have been created and you could not create one if you so desire. Why does the universe have to have a creator if a god doesn't?
Arguing against the Big Bang doesn't help, because if there wasn't big bang type singularity, then there wasn't a beginning to the universe and thus no creator. If the curvature of spacetime is closed and curved, then there definitely was no singularity and no possibility of a creator. The further back in time you go, time bends about itself and you start going forward in time.
So the time when the singularity "would" have happened actually never happened. By analogy, if you stepped in a hovercraft, pointed yourself north and kept going, you would eventually end up at the south pole. You would never end up on Polaris.
There was never a time when there was nothing. See also the Blind Watchmaker and Ultimate Boeing 747 Gambit.
I see a house, I know it had a builder, who built it with bricks. I can even tell you how he built it. I see a painting, I know it had a painter, who used a paint brush and paint.
But when you see a universe, and think it had a creator, what exactly did this creator create it with? How did the creator create? Creations always have several things in common: They require a creator, and they require materials and tools to be created.
Even something as simple as the wheel follows this example. The builder didn't magically poof the house into existence out of thin air, just like the painter didn't poof the painting into existence; but the creator would have had to somehow magically conjure up the entire universe into existence out of nothing, since tools and materials were obviously unavailable as the universe was not there yet. This would mean that the universe is not, itself, a creation; and that the comparison between the universe and paintings, houses, etc. is false.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
