We don't. If you know some place on Earth where these odd "beings" are native, please let us know.
Due to time dilation at extreme speeds, a trip to a star system 500 light years away could pass as if it were ten years for humans aboard the vessel. The round trip might take 1000 years for the folks on Earth to see the ship return, but the original crew would have only seen 20 years go by. Einstein's theory of relativity is why.
20,000 miles per hour is hardly the upper speed limit for humans today - the Parker Solar Probe surpassed 153,454 miles per hour, and with the theoretical solar sails and ion drive engines we might be able to reach more than 99% of the speed of light.
There are literally hundreds of billions of galaxies, and billions of stars in each one. No matter how rare intelligent life might be, it is a certainty that other intelligent life does exist elsewhere in our galaxy and universe.
Now consider that our planet is relatively 'young' by galactic standards, there are many others which are double and triple the age of our own. This makes it very likely that other intelligent life will be more advanced than we are technologically. They very well could have found ways to solve the problems of the vast distances involved with interstellar travel.
Sure, I know exactly where such creatures might reside. They might be in other dimensions, which have been predicted by String Theory, that are intertwined within our own three dimensional space. They might be just as trapped by earth's gravity as we are.
You gotta be pretty reckless to assume "space aliens". Like you say, look at the distances involved.
