What do you think about life exist in other galaxies?
A galaxy is a gravitationally bound system of stars, stellar remnants, interstellar gas, dust, and dark matter. The word galaxy is derived from the Greek galaxias (γαλαξίας), literally "milky", a reference to the Milky Way.
There is no evidence that life exists elsewhere in the universe other than here on Earth; but, “Absence of evidence is not evidence of absence” (Carl Sagan, US astronomer & popularizer of astronomy 1934 - 1996). #Space#LifeExist#Galaxies
Life probably does exist in other galaxies. In science, there is no real uniqueness to something. In fact, if the universe prefers something over something else (in this case our galaxies vs the other billions of galaxies) it would be mind-boggling like the oddity of particle spins.
