Ah. Someone with actual data. Thanks SZ.The way that we know is by hypothesis and testing. There are still unanswered questions which is why it is still called the Nebular Hypothesis, some basic reading:
How Was the Solar System Formed? - The Nebular Hypothesis - Universe Today
Nebular hypothesis - Wikipedia
If you want the data I suggest that you go to Google scholar. I don't think it would do you much good since you are probably far from qualified to analyze it. I know that I am not qualified to do so. You could ask @Polymath257 , but it might take a long long time for him to explain all that we know.
So they don't know. They assume, as I rightfully said.
They just have a widely accepted idea.
Looking at the problems associated with the idea, I think one more is in order - explaining why the earth has its tilt and location, and relative distance from the sun.
Oops. It just happened to be the lucky planet, that makes it possible for us to be here... and thank Go... Thank nature for Jupiter.
Lord help us.
