My first landing on Earth

These are notes dropped by an alien, I just found them, or may be I'm lying, as usual.

My first landing on Earth.

My heart is empty, and barely beating

Barely beating, inside my chest

My chest will need, a heart replacement

Replacement, or at least some rest

Some rest, because I lost directions

Directions, time may suggest

Suggest landing, on an evil planet

A planet that failed, every test

Test as bad as, embracing nonsense

Nonsense created, without request

Request for angels, turn into demons

Demons thriving, for just one quest

One quest for demons, turn into Earthlings

Earthlings live, hate and detest

My heart is empty, but since when an alien

Had a heart beating, inside his chest?
