The causeway is a construction ramp/ it was built before the pyramid/ it is on the same side as the river/ the stone came from the east (from the river)/ All four of these statements are logical and evidenced. Which is tripping you up?
The reason I removed the last two is obvious.
The causeway is a construction ramp. NO PHYSICAL EVIDENCE
It was built before the pyramid. NO PHYSICAL EVIDENCE.
As far as getting tripped up, this is the second time I have replied to your questions with the same answer.
