Dont laugh but i believe in the Annunaki thing, think about , they found a Stone of the sumerians who lived way back before the egyptians and mayas,also some things in the Egyptian Mythology point to Snakes and reptilians even their gods head a snake on their crown and when u study it a little bit ull notice all Religions have their Origin in the egyptian mythology u can similiar all things even in the satanism u will ever come back to the Egypts.
I dont believe all what David Icke says neither read his books and all but its just so obvisiouly, and this creatures are under us , i think they have like a time machine , or something but they are in another dimension, thats why we cant see them.
When u think about we got in a few million years from a fire to a touchcomputer ,what technique will they have then
and why shouldnt it be possible to change the materia to do things we cant imagine.
I Think the Egypts met them and used their intellegence to build this things.
