More simple explanation: Life is out there, it's just too far away to detect, or to visit us--and will ALWAYS be so, because you can't cheat Newton and Einstein. An alternate "simplest" explanation (though less likely) is that we are first.
To suggest that ET hasn't come to visit us because we are "too violent" or whatever, and that they are masking their presence is definitely NOT the simplest explanation--it suggests that every nearby alien species has agreed to isolate us, and every member of those civilizations is on board with the idea. No one is out there playing with an RF emitter in the VHF band, Harry Mudd hasn't stopped by and spilled the beans, no one's even accidentally done anything to give the game away.
Sorry, I'm just not buying that.
