I don't think anyone in this forum is able too explain what gravity is.
And I don't think anyone have a drill with camera big enough to dig 2,5k kilometres too prove earth's core. There are so many things that are a complete mystery in this world. But one thing we know for sure is that earth are round and moon and sun are not that close. Do you're math it's simple just use parallax.

Gravity is an attractive force between two bodies with mass. :)

So, could we say that between you and I there is gravity?

vanished boats that appear back into sight when viewed through binoculars or telescopes, but we know for sure that earth is round...

That is a literal fact. Gravity is the force of attraction between all masses across all of space-time.

All things with mass, effect all other things with mass, even if only very remotely.

Gravity's force might be weak, but it is persistent.

There is! :)
We can calculate it if we know both of our mass, and our distance through Earth :)

man can't drill past 12km into the earth, but we know for sure earth has a molten core...
lasers across lakes and rivers showing zero curvature, vanished boats that appear back into sight when viewed through binoculars or telescopes, but we know for sure that earth is round...

your logic is astounding.
