Who said be accepted?Forget about Egypt for a second, what makes you think your logic here is reasonable? Any creative thinking going on take has to take place within the context of available evidence. Postulating theories is one thing, asking for them to be accepted without being vetted is absurd.
It's reasonable because its makes sense if you consider different things, especially when I just gave you multiple links to support my theory. You are just ignoring them. I even explained in depth why I think this, and you still ask me what makes them reasonable!
Do you know what reasonable means? Let me show you:
Reasonable
adjective
1.
agreeable to reason or sound judgment; logical:
I showed why they could have walked to these places within a year. I showed why there could be evidence in the sea. I showed why I think they could have travelled along the coastline to west Africa. I showed why they could have went through the Sahara.
These are four things I gave to help prove my point, yet you ask me what makes my theory reasonable?
Just forget it.
