I don't have proof and the general consensus with in geocentric research is all over the place, but with that said i can give you my own theory..

all through out history theres a common trend that keeps popping up. a third celestial body (sun, moon and black sun/dark sun/nibiru ect) theirs different names depending on the source.

anyway their has to be something creating earths magnetic field, ancient peoples called it mount meru and it was located at the north pole or center of our plane (whatever works for you)

i think periodically, this mountain or giant iron lodestone goes thru magnetic discharges resulting in huge chunks of said mountain or stone blasting off pieces of iron into low earth atmosphere. When it rains back down we see it as meteorites
