Aliens exist as the universe is just too unfathomably big to be devoid of life except for our pale blue dot... But also because the universe is so big, and the distance between things is so vast, I highly doubt Aliens have visited Earth
Man, also, once stood on the shores of an ocean, looking out, and thinking it was beyond impossible to traverse across it in a reasonable amount of time.

Not necessarily as the universe hasn't been receptive to life, nd intelligent life seems to need millions of years to evolve
Also that vast distance doesn't change, just the technology so it would still be a vast distance to travel
