Hehe, maybe... the issue is the size of the universe, earth is barely a speck of dust... there are more stars in the universe than grains of sand on earth.... why would aliens care about a speck of dust with some ants on it....

Don't get me wrong, I definitely believe there is other intelligent life in the universe and maybe some of them are capable of intergalactic travel, I would love to meet them some day.
