How can anyone possibly deny the overwhelming evidence for the existence of the Morrigan?

This trio of battle goddesses has been proven to exist countless times over the millennia, and only a fool would question their existence at this point. Here is a painting of them, which proves my point. Because how could there be a painting of something that doesn't exist?
On the left, we see Badb (pronounced Bev). In the middle, we see Macha. And on the right, we see Nemain.

Not only have millions of people believed in these beautiful battle goddesses over the years, there are places named for them, places where legendary battles took place.

Present your evidence against them, Christians. I'll wait right here.
