I don't believe in a god/ a being that created the Universe. But I don't think that believing in one is bad. If it's Christianity, Islam or Buddhism, or something completely different. There are even people theorizing about the Universe not being real, but instead being a computer simulation made by higher beings.
And if someone thinks that this sounds ridiculous, then think about your own opinion about this. For example a higher being that created all of the universe? Sounds ridiculous.
But a Universe that exists out of pure Coincidence 13 billion years ago from a single point smaller than an atom? Sounds ridiculous either.
Everything we theorize about what the origin of the Universe is, is just a desperate attempt of figuring out what's really going on in our world. We are such unsignificant little creatures in that uncomprehensably monstrous/enormous universe that no language could actually describe it's collosality of.
We as a Species will most likely never figure out what the Universe is about. So, speculating is the only thing we can do. What we can't do is fight about it, that is just stupid. It would be the same as two ants discussing wether the earth is flat, or donut shaped.
From the ants point of view the earth could be everything, it could be the whole Universe, or it could be only 1 kilometers wide, which is enormous for the ant because it's so small and because it will never be able to travle that distance in it's lifetime. The Ant probably thinks that they are the most intelligent and advanced creature on this earth. I mean they only know about all the other insects, which they are far superior of. And because they didn't observe anything else yet, they must be the most intelligent creature living on the earth, right?
We are little Ants, trying to figure out what the Universes shape is, Some scientists believe that it's flat, others believe that it's donut shaped.
