Her interest doesn't surprise him, and he's more than content to help sate her curiosity. "Some of them aren't humanoid, but a lot of them are. The Horta are probably the most alien race we've met so far - they're silicon-based, basically living rock slugs the size of a small pony." He isn't sure she knows what a pony is, so he uses his hand to indicate a height of a few feet off the ground as a visual aid. "The Andorians are fairly humanlike except for blue skin, antennae, and four sexes. The Tellarites aren't entirely humanoid... more like bipedal pigs, I guess. And they love arguing. It's like their national sport or something."

In turn, he's fascinated by her own history, especially the Earth part of it. "That's great. Religious texts aren't usually completely literal, but there's usually at least some truth to them. What kind of proof did you find?"
