Would aliens want to meet us? (part 2)

The biggest reason aliens are unlikely to bother with visiting earth is that they have their own problems to deal with. Just look at humans—we are constantly facing conflict, embroiled in wars and disputes, all while dealing with dwindling resources, pollution, the challenges of energy and food production, natural disasters, and disease. Most of our effort is focused on just surviving here on our own planet, so much that America's space program, NASA, was scuttled to focus largely on environmental concerns. If not for private entrepreneurs funding companies like Space X, we might never make it past our own moon. So why should aliens be any different? In the movies, we always see the aliens as one united entity—they don't ever seem to have factions--it's like the alien planet is all one big happy country and the aliens have all learned to work together and put aside disagreements. We suspend our disbelief when seeing this in movies by concluding that they are more advanced than us, so they're more enlightened and have learned to work through all their problems. Yet we somehow also accept that such a peaceful, enlightened race has decided to invade our planet. What possible reason would they want earth for? More on that, tomorrow...
