Why Does Our Universe Exist?

We have such an incredible lack of knowledge about the early universe that it's useful ti come up with these arguments to evaluate them. We can't go back in time and see what actually happened, or journey around the whole universe and gather the daty we need. So until then, we just are stuck here on earth in our brains,. thinking about the origin o the universe and convincing ourselves that maybe we're making progress. Yes, tat's a good point. David, you just woke me up from my nap. I was doing some thought experiments. All right, i guess maybe we just have to keep our fingers crossed.
