Please don't come, it's a trap! This is a massive shithole we live in. We have multiple alien factions trying to gain control of this contested planet. Our sea water is highly irradiated. We have weather weapons causing natural disaster. While our technology level appears to be law, this is but a illusion caused by our merciless ruling government. By-the-way, the Annanunaki space-station will be arriving shortly, and those on-board won't be happy to see another another competitor.

However, your most dangerous threat is not from these factors, but a paranormal phenomen called the GLP effect, that is, we have the power to twist the fabrics reality just by calling it "bullshit". Your space ship that can blot out the sun will be wiped into oblivion if we simply deny its existence.
