What tangible proof do we really have that the earth is a sphere?
Have you ever actually seen -official NASA- footage of a spherical earth, or a spherical moon for that matter?. If not, how come? And if you have not seen such footage, then how can you be sure the earth to be spherical? What tangible/empirical proof do you have? Does such footage exist in the first place? If not, how come?

So-called ecclesial books tale about cosmology, anthropology, ontology - so, what's all the commotion about then?
As the great philosopher P pointed out:
Isn't life wonderful B? Just think
we started out as lab mice forced to
spend the whole day working our way
through frustrating mazes that went
absolutely nowhere. Now we get to do
what humans do!

I find that most of your questions are "loaded", so to speak. Quite often they seem to be bait waiting for the most subtle ambiguity and improper response to be pounced on.
I have seen evidence, and deductive reasoning, that indicates with a high likelihood (a likelihood that approaches 100%) that the Earth is round. Not just round, but close to a sphere with slight bulging around the equator and compression at the poles. The most telling evidence being the shape of the shadow created on the moon during a lunar eclipse. There are other bits of supporting evidence for these ideas as well - from astronomy, travel, maps, satellites, and other planets & moons observed in the universe. But if you'd like to believe otherwise, that is your choice.
Since you asked.
