im not sure if this is the right section but if you dig and dig under the earth surface how many miles low is it
as that english guy david icke i think his name is said theres a reptilian race about 100 miles below us.

The Earth is 12,742 km in diameter.

Divided that by 2 and that's how far down you can go before you start going 'up' again.

The outer core takes up 2890–5100km of depth, and the inner core is approx. 5100–6378km, so that's pretty much a no-go zone for most living things.

i would advise you to research david icke and decide if he's someone you want to believe in. since the crust gets to be about 50 miles/70km at its thickest, it seems unlikely that something is going to live at 100 miles down. certainly it would be swimming in magma.

david icke is the dude who talks about reptilians :s

how would it be more fantastic that there is life in the middle of our earth then life on top of it?
how would it be more fantastic that there could be life in magma then life in air/water?
how would it be so fantastic that we are wrong about the earths layer?
what were the methods used to calculate how deep the crust is, and how accurate can we expect it to be?

sorry if my questions is stupid, i just need some help closing my mind alittle bit more.. ty in advance for trying (sorry for the snarcy comment.. is snarcy even a word btw or did i just invent it?)

hmm sorry for keeping this going, i guess evasius allready gave you the answer you were seeking, just thougt the last responses were alittle sad to be finishing words
