There are likely other "Earth-like" planets in our galaxy, but none that we know of. Earth's conditions are particularly hard to come by. Its the right size, has the proper material components, and is the right distance from our sun to allow life to prosper and evolve. Scientists have estimated the number of these types of planets, but we really have no way to know without more information. Its also possible that planets with completely different conditions could support a different type of life. We are familiar with carbon-based, oxygen/CO2 consuming cells... but who knows what other life may have developed under different conditions.

Almost certainly. Astrophysicists are discovering more and more planets; there are trillions of stars; so the odds against life existing SOMEWHERE in the Universe are unimaginably huge.
That doesn't mean we'll ever come in contact with an intelligent alien race, however. Not only is space mindbogglingly immense, so is time; and the odds against finding an intellectually and technologically compatible alien race close enough in space AND time that we can have two-way communication is also very, very, VERY large.

Not that we know of currently. There is evidence of previous life on an early Mars (bacteria imprints in the rock), but as of now, we on Earth are the only confirmed living things in the solar system. Well, except on the spaceship they send plants, people, etc. up on, but it originated from Earth.

lets take this logically , waht is life , is it a liveing being ,it can be a virus also , a virus is dormant for millions of years and then it can come back from the dead when something triggers it .
So does something other than earth have a life ,of course there has to be .

Hi. Probably, but Earth is very rare and precious. We still don't know all of the species on this planet.

Yes, and we may never know because they are too far away

None that we know of yet. However, just because we haven't discovered it, doesn't mean that it doesn't exist.
