The Earth is flat and you know it, so stop denying it like the rest of the sheep!

Gravity does not exist, it is governmental propaganda to make like you believe everything they say!
This "science" that is said to be proving that gravity exists is FAKE.
Stop believing these who are calling themselves "scientists" and trust the facts.
The fact are that the earth is flat, there NO WAY the earth can be round, its just not possible.
I am Right. you are all for thinking the earth is round!
History is a lie! there was never a world war because that can't physically happen
It's a holo-gram that's being projected onto the dome that covers the earth
The Government is lying to you and you are all falling for it!
