Oh well if it's not a game, then I say we use flashlights at night and use the sun during the day. We could use the sun's energy to light bigger stuff at night.
If we lived in Venus, then we would have to take over the Venurians (aliens), with our weapons of massive destruction and the planet would blow up so we had to find somewhere else to go to.
What if ... this wasnt a game as tennisman24 said and it was really a question...
