But we all know creationist like to use the sea shells on mount everest argument as evidence that Noah's flood was real. anyway I saw one creationist post that when clams die they open up and that the clams found on everest and other mountains are all closed therefore he reasons they died under pressure (from a global flood) and rejects plate tectonics. what is the answer to this? how can i rebut this claim?

This is probably what they said. Everest didn't exist before the flood. its just crumpled up land from the crashings etc of the land masses during the biblical flood. So as they rose they brought up what had been thrown on them . All this while under water. so the great water pressure or the water prssure on sediment didn't allow the clams too open as usual upon death. Thy were entombed before opening and this entombing was the origin of their instant fossilization.
so they not opening is a clue that such a great number could only of been instantly covered and killed under sediment or water pressure.
A fair point based on observations of nature.
