What is the probability that there is another earth like planet in the universe?

However, if by the same you mean that life should exist there, then we have no idea what conditions must be met for life to arise, even in the presence of necessary molecules and at favorable temperatures. Miller's 1952 experiments demonstrated that amino acids could form in the right conditions, but not life. Close, but no cigar.

With billions of galaxies in the observable universe and billions of Earth-like planets in the Milky Way galaxy alone, scientists estimate that there could be billions of Earth-like planets in the Milky Way galaxy alone. Despite the limitations of current scientific knowledge and the vastness of the universe, the probability of another Earth-like planet existing in the universe is thought to be fairly high. This is based on observations from space telescopes and statistical models.
