Is there any other sign of life anywhere except on earth?

Answer 1

Life on Earth exists in a single solar system revolving around a star we call the Sun. Our galaxy is called the Milky Way Galaxy and it consists of around 200 billion other stars all with there own planets that make up their solar system. The Universe itself consists of hundreds of billions of galaxies all with billions of solar systems. There is no need for other signs of life when you consider the gigantic size of the universe. Other life in the Universe is a guarantee.

Answer 2

Iron was an abundant material when the solar system formed. It is present in all of the terrestrial planets and asteroids. Uranus and Neptune are believed to have an iron-nickel core, so it would not be unlikely that Jupiter and Saturn also had some iron in their core.

But Mercury, Venus, Mars and the asteroids in the asteroid belt may use to have life and water. Apparently on mars there is dried up valleys and seems to have life ages ago

Answer 3

So far, no signs of life have been found on other planets. The best that scientists can do is speculate on whether it does or has existed, based on conditions and estimated conditions of other planets and exoplanets.

Answer 4

As of now, there is no definitive evidence of life beyond Earth. While scientists continue to search for signs of life on other planets and moons within our solar system, and even in other star systems, no conclusive proof has been discovered.

Answer 5

So far, no。　There has been no sign of life except on earth.

That still could change though.
