Alternate Theory (This is serious, don't lock)

The theory is simple: there is no earth. Nobody has ever seen Earth, and therefore, nobody can claim it exists, we actually live on the back of a giant turtle, whose shell is covered in rocks and dirt and plants.

The Iroquois Creation Story:  In the Iroquois Creation Story we are told of a world that exists high above the world we know today. Life in Sky World was much like it is on earth. A woman came down from the sky one day. She landed on a turtle's back. This turtle came to be known as Teegeeack, and on the turtle's back, the sky woman founded civilization.

How much support does this theory have? Let's see:

This poll shows that the majority of people in the world don't believe in earth.

Mathematical Proof:

1*0 = 0*0
therefore 1 = 0

There is 1 earth (supposedly), therefore there are actually 0 earths.

Boring and unoriginal.
Seriously, this stopped being funny since forever.

Now go take your meds.

The sky is unending, and therefore doesn't exist.

Wow!  How unoriginal!
