Fake Human

It has been traveling throughout the vast Milky Way Galaxy in hopes to find a suitable planet to hide within. Now after hundreds of years of search, it has finally found a suitable planet called 'Earth' where beings called humans reign on top of the food chain, but that is soon to change with the landing of a capsule from outer space. Within this capsule, an entity steps out. Who is the new Apex Predator now? And what is this alien's goal?

This is my first novel and I would appreciate your objective feedback (It will be heard and taken into account), after all, what am trying to do is improve my writing in hopes of giving my readers an immersive and enjoyable adventure.
