Easy answer, YES. Who is to say we are the only life in the universe, when we were created ourselves either through a bath of chemicals and minerals or brought here by whatever we are not the only life in the universe.
There are more stars/suns in the known universe than there are grains of sand in all the world's deserts combined. That being said, it's almost impossible for there not to be life out there. Will we ever see it(at least multi-cellular beings), I highly doubt it. There's just too much of a distance between planets and solar systems. And current science hints at the universe continuously expanding, as if the shock wave from the big bang is still being sent outward.
Yes, there is life everywhere.

Among these, the famous specimen Allan Hills 84001 has a different rock type than other Martian meteorites: it is an orthopyroxenite (an igneous rock dominantly composed of orthopyroxene). For this reason it is classified within its own group, the "OPX Martian meteorites". This meteorite received much attention after an electron microscope revealed structures that were considered to be the fossilized remains of bacteria-like lifeforms. As of 2005, scientific consensus was that the microfossils were not indicative of Martian life, but of contamination by earthly biofilms. However, in 2009, new analyses ruled out earthly and non-biological origins, presenting strong evidence of life on Mars.[18] ALH 84001 is as old as the basaltic and intermediate shergottite groups — i.e., 4.1 billion years old.
In March 2004 it was suggested that the unique Kaidun meteorite, which landed in Yemen on March 12, 1980, may have originated on the Martian moon of Phobos.[19] Because Phobos has similarities to C-type asteroids and because the Kaidun meteorite is a carbonaceous chondrite, Kaidun is not a Martian meteorite in the strict sense. However, it may contain small fragments of material from the Martian surface.
Bacteria fom Earth can survive in space, it goes into a type of hibernation mode. They've done studies with the space station to prove it.
So, now, they just have to arrive at a consensus as to what is alien bacteria, and what is earthly contamination. I suppose.

A NASA research team of scientists at the Johnson Space Center (JSC), Houston, TX, and at Stanford University, Palo Alto, CA, has found evidence that strongly suggests primitive life may have existed on Mars more than 3.6 billion years ago.
The NASA-funded team found the first organic molecules thought to be of Martian origin; several mineral features characteristic of biological activity; and possible microscopic fossils of primitive, bacteria-like organisms inside of an ancient Martian rock that fell to Earth as a meteorite. This array of indirect evidence of past life will be reported in the August 16 issue of the journal Science, presenting the investigation to the scientific community at large for further study.The two-year investigation was co-led by JSC planetary scientists Dr. David McKay, Dr. Everett Gibson and Kathie Thomas-Keprta of Lockheed-Martin, with the major collaboration of a Stanford team headed by Professor of Chemistry Dr. Richard Zare, as well as six other NASA and university research partners.
Could be wishful thinking as well, but I seriously doubt that.
Encleadus probably has some bacteria brewing now. Only my opinion.

The most abundant, or the most diverse habitats on Earth are near volcanic vents at the deep sea rifts, and sea mounts.
Volcanism is the norm on nearly all the planets and moons. Nearly all of them exhibit some type of volcanism. Water is pretty normal stuff too. So is the Suns radiation.
So, the only real question is, do you believe in an infinite universe, where evolution has taken on all possibilities, offering every imaginable life form possible, or a tiny little finite God Biff Boom Bang, magical explosion Universe, where odds of life happening are truly one in a Universe.
