Fear isn't really...a thing we can taste? I don't think? Whatever Pennywise is, I think he's got to be a different species than us.

And yeah, we're omnivores, so we eat the same stuff pretty much. I mean, we're more likely to want to eat insects, but overall whatever a human can eat, we can eat, too. But there's a lot of reasons to come to Earth. I don't know why the Reptilian government is interested in it, but they are. And then not even counting that, it doesn't do any good to have ships that go through space if you don't visit the planets you end up at, you know? And Earth is pretty neat, and has a lot of novel foods you can't get anywhere else, like coffee and chocolate.
