They didn't. Most people's lives remain unaffected by anything beyond geosynchronous orbit. (Geosynch is the altitude of communications satellites.) Even for those of us who are fascinated by astronomy and space travel, information about distant galaxies is unlikely to affect us personally in any significant way.
But knowledge often turns out to be practical and useful in unusual, often in unimagined ways.
Comment: That's true up to a point, but I think there has been an important
psychological effect. The proven size of the Universe became much
larger and this has deeply affected how humans feel about their
significance in the Universe. OK, a lot of people don't think about
it, but if you do it's truly staggering.
Edwin Powell Hubble, the American astronomer, demonstrated the existence of other galaxies besides the Milky Way.

Mister Edwin Hubble did just that, before the 1920's, many astronomers thought that our galaxy included everyobject in space, in 1924 Edwin Hubble proved that other galaxies existed beyond the milky way
He invented a system for classifying galaxy morphologies (shapes). The Hubble Space Telescope is named after him, but he did not invent it.

In the late 1920s, the astronomer Edwin Hubble discovered that most of the galaxies he observed were moving away from Earth.

BELLY!
Edwin Hubble invented a simple classification system for galaxies. The Hubble Space Telescope was named after him for his discoveries in astronomy.
Edwin Hubble was an astronomer.He proved that there are a lot of other galaxies out there.He proved that those galaxies are moving away from us and the universe is expanding.

Edwin Hubble was famous for measuring the red shift of distant galaxies and interpreting that as evidence of the expansion of the Universe.
Edwin Hubble proved that there are other galaxies spread throughout the universe, and that these galaxies move away from each other as the universe expands. He further found that the galaxies in the outermost areas of the universe move faster that those nearer the middle, a feature in his Hubble's Law.
