Question

Some lines about aliens doesn't exist on the whole galaxy about 100 words​

Answer 1

Answer:

No-one said that aliens “don't” exist in the whole galaxy. Scientists find the probability of life on some other planets too which are beyond the milky way galaxy. A fact on which debate is now standing upon is- the black hole is the “merging point of 2 different galaxies”. As no-one has ever returned from there, it is difficult to say about the world with life beyond our knowledge. Aliens may exist in some unknown part of the universe.

Scientists asume the stone pieces which look like meteors' or asteroids' pieces but they aren't, to be of some unknown planet.
