The giant cell-damaging ball of light in your sky is moving. Is it supposed to do that.

"- oh it actually isn't, we're moving. Common misconception."

"...hello? Aliens?"

We are trying to figure out whether we should be worried, and your answer isn't very helpful for figuring that out, and I am confused.

"...the sun is normal, uh, far as I know."

Well. Okay. That's good. Sorry. If something like that showed up in our sky it would be very worrying.

"Your planet just sorta... hangs out? Sunless?"

Definitely sunless. I don't know about - hangs out - I haven't ever really thought about it - I guess it can't just go on being world forever so probably, yes.

"Sounds, um, dark?"

Oh no there are Trees.

"Really? How do you have trees without a sun?"

The Vala of growing things, Yavanna, made the Trees and also all the rest of the trees.

"I don't know that - is it a word if there's telepathy? Since it's not in words? I don't know that thingy."

It tries to map to words where it can. The Valar are the creators of the world and the instruments of Eru's will in the universe?

"Dunno that thingy either. Bella the aliens are religious. Yeah. I dunno."

The aliens glance at each other. One of them hops rocks to a less precarious one. Well. It's very nice to meet you.

"You too! So what brings you to Earth?"

This was not deliberate. At all. 

"Are you like, space exiles or something?"

I think probably this was an accident. And I don't know what space is.

"Well, where are you from if you aren't from space?"

Valinor.

"Which iiiiiis..."

Like so: ridiculously bright and glittery and beautiful, intricately carved stone everywhere with glass and metal for decoration but not, apparently, for utility; wide streetsful of tall pretty people. Singing. Lots of singing. Picturesque wilderness. The Trees.
