Today’s second glitch:
The whole race? Meaning all of ’em? Wow… *shakes head*
Alien isn’t a proper noun; it’s a common noun/adjective. Don’t capitalize it.
Also, it’s okay to say species instead of race when talking about sapient lifeforms who are, y’know, actually of different species. (When writing science fiction, maybe you want to surprise your readers and use the scientifically correct terms for some things.) Saying species DOES NOT mean you’re calling them animals, non-sapient, etc. (“I ain’t part of some species, damn you!” Um… Okay, maybe you’re not. But every other biological lifeform — even the other slime molds — are, so please respect their right to be a member of a species if they want to be.)
Otherwise… Well, I’m sort of winging this on word choice and such, because I can barely figure out what the writer was probably trying to say.
Members of an alien species come to Earth and challenge humanity to an Olympics-style competition. There will be six games, three of human invention and three invented by the aliens. The winner gets to keep Earth.
(This is what I mean when I say that, if the reader can’t even find your story under the wonky sentence structure and poor word choices, etc., it doesn’t matter if your idea is the best in the world, because the reader won’t know what you’re talking about.)
Don’t forget to capitalize the name of your (or anyone else’s) home planet!
