Assume for sake of contradiction that tides are real.

Fact 1: High tide is pointing towards the moon, always. So, at high tide, the moon is overhead. At low tide, the moon is off to the side (not overhead).

Fact 2: The moon goes around the earth a lot slower than the earth spins in place. About thirty times slower. So we can more or less treat this like the moon being stationary, and the earth spinning underneath it. So the point of highest tide is basically stationary, and the earth is spinning underneath it.

Fact 3: High tide goes all the way around the earth each day. It keeps up with the moon, and does not fall behind. Full circuit in 24 hours. (again, it's a tiny bit more than 24h because there is also the moon going around the earth, but it's close enough.)

Fact 4: That comes out to over a thousand miles an hour, at the equator.

Fact 5: Mass is actually being transported. This isn't like ocean waves on a beach, where waves exist but no mass is actually moving (the ocean is not steadily making its way up the beach, but tides ARE steadily making their way around the earth). The ocean that I can see is actually becoming more massive, with more water physically here, at high tide versus low tide. Water is incompressible: lakes don't get tides, only the ocean does, because water can be pulled and dragged along by the moon's gravity all the way around, forming what we call "high tide". (okay, some really big lakes do get tides, but that's just the water rushing slightly to one side or another, wherever the moon is pulling)

Fact 6: Therefore, there is an immense amount of water going around the world at a thousand miles an hour.

Fact 7: The fastest measured ocean current in history is about five miles an hour.

Contradiction.
