...who is this Deepak person who has written this stuff??

The Egyptian heiroglyphics are especially convincing. If you check out a few symbols from this list, you would realise how much advanced technology they really used.

Character F46 shows they had knowledge of the use of paper clips.
Character M37 shows they made and used those styrofoam coffee cups.
Character N40 & W25 show they had advanced transplant techniques.

Wow, things we didn't know about ancient cultures, eh? ...thanks for the topic, but now I will worry about takeover by the lizard aliens every night.
