Come on, just go outside and look at the Moon.
Yeah I've done that. And when I look at it, it's hard to believe we sent men there, which makes me question NASA more, who seems to be the leading agency that pushes the globe earth concept on us. Looking at the moon doesn't help me trust in mankind.
You can see the shape of the Earth on the Moon's surface - the curved shadow.
Maybe it is, and if it is, then perhaps that's strong evidence for the globe Earth theory.
But how do you know that's the Earth's shadow?
Is that a fair question? You're schooling me right now. Is it still fair to ask questions in school?
All that is needed is to understand elementary physics about how shadows are cast. Yes, there is some light behind the Earth, it is called the Sun.
Well for me, more is needed. I'm not blindly accepting I'm looking at a shadow (perhaps the moon is its own unique light with an ambiguous/tricky pattern) ((God made a lesser light to rule the night)), and I don't blindly accept the shadows I see are from the objects people tell me they are from.
