Nothing about our existence is amazing and miraculous if the popular multiverse theories are correct. In that case, we're just in one of a trillion-trillion to infinite copies of this universe that happens to look this way.
I don't understand why people say that.
Even IF the multiverse theories are right (good luck finding evidence for that) our universe would still be amazing.
Sure I'm "just" an animal, but the stars at night are still amazing, flowers are still amazing, my wife is still amazing and so on.
I don't know of any evolutionary reason why humans should find the stars and nebulae beautiful and even if a reason was found I still see no reason why suddenly they would not be beautiful anymore.
