Quotation from Weird Water Events:

"No matter what phase water is in, the water molecules stay the same; they just move differently." If water molecules always stay the same, they cannot disappear when water changes phase. Therefore, the evidence refutes the claim that "molecules in a substance disappear or no longer exist when a substance changes phase."
This evidence supports the claim that the lake evaporated.
This evidence refutes the claim that the lake froze.
