I did this experiment where you put a drop of carmine solution next to the crayfish and the solution goes in its gills and out of its mouth. And I wanna know why it breathes in that manner

Whoever told you that? Crayfish use several of their appendages not only for eating but also to help move water over their gills for the purpose of oxygen exchange. The mouth is only used for eating.

because that's the way god made them
or because they evolved that way to adapt to their environment, just like everything else
or maybe because they live in water, yeah, that's it, water . . . hehe
