So why can't I see stars during the day?
Because the much brighter light from the sun scatters through the atmosphere washing out the much fainter stars.
It is clear to any thinking man that the earth is flat.
Quite the opposite.
All the available evidence points to a round Earth, not a flat one.
It is clear to any thinking person that Earth is round, not flat.
The conjecture of a spotlight sun is well supported in peer reviewed research.
By "peer reviewed research" do you mean wild claims spouted by FEers, or actual research?
Because the actual research shows the sun is a giant ball of plasma.
The only which appears to support a spotlight sun is the wild assumption that Earth is flat, which then needs some nonsense to stop the light from reaching everyone all the time.
Perhaps you should try using a telescope. You know, I'm not put on this earth to spoon feed Earth: Not A Globe to angry globularists.
The sheer difference between just before and just after sunrise is far too great for the atmosphere to be a cause.
If the sun was a spotlight it should vanish high in the sky. If it was the atmosphere being too thick, it would fade to a blur high in the sky, gradually growing fainter against the surrounding sky, until it is too faint and distorted to make out.
That does not match what is typically observed. Instead what is observed is the sun appear to set beyond the horizon, with Earth obstructing the view.
