I don’t think you can know for sure what happened in the past by looking at the present. We hear cosmologists tell us what happened 13 or 13.7 billion years ago. But are you sure we can trust it.You know what else doesn’t make sense? that the universe doesn’t follow the universal laws of physics. Those laws say that given its age since the big bang, the rate of accelerated expansion of the universe is still too high and the universe should have torn itself apart and become a soup of particles. Why it hasn’t is a scientific mystery.
Let me give you an example. Suppose we know that a glass of water has been sitting on the table for a while. And we know that the temperature of the water is 60 degrees Fahrenheit while the temperature of the room is 70 degrees Fahrenheit. Can you say what was the temperature of the water say 2 hours ago? At first thought, you might say yes, we can apply Newton’s Law of cooling and some information about the temperature 2 minutes ago (or 2 minutes from now) and this will give us the temperature 2 hours ago. But will it? You see 2 hours ago you could have had a glass with only liquid water at a cooler temperature which then became 60 degrees because of the surrounding temperature of the room at 70 degrees. But there is another possibility. And that is that 2 hours ago the liquid water could have been at 90 degrees F but that there were ice cubes in the water which melted and caused the temperature to drop to 60 degrees F. So just knowing that the temperature of the water in the glass is now 60 degrees F is not enough to know what the situation was 2 hours ago. there is more than one scenario which could have occurred. The universal laws of physics, which you are talking about, cannot tell us what was the situation in the glass of water 2 hours ago.
