barry i want to travel to Alice Springs with you to look for Aliens

why would people have preference for one area over a planet over any other? like if we found a 3 mile cubed area of pure gold on mars for existance what would be our reason for going there. its crazy and i just dont get it

i'm assuming if they've mastered interstellar space travel they couldn't give a hooplah for our resources
maybe they got bored after landing in a desert, thought our planet must suck and all looks like that, and left without making contact
