Let us suppose the plagues happened, which I think is plausible, why should I believe they were sent by God or that Moses predicted them?
Far more likely that they did happen and some Jewish writer incorporated them into his story, and just made Moses up.
How many wheels have been found? The link is vague; it could be thousands, which would be significant, it could be two, which would not.
Ron Wyatt and his team have found the remains of chariot parts, chariot wheels & skeletal parts of horses and men, ALL CEMENTED IN CORAL. Because of this, it is difficult, if not impossible, to extricate them without destroying them.
Ron Wyatt did extract the hub of a wheel with parts of 8 spokes attached and presented it to the Egyptian authority. This was sufficient for Mr. Nassif Mohammed Hassan to identify the dynasty from which the wheel came.
To date, the chariot parts have never been found in the Red Sea anywhere, except this site!
