Could there be lifeforms on another planet ?

1. Extremophiles on Earth
One of the big questions is whether life could evolve and survive on a world radically different than Earth. The answer appears to be yes, if you consider that even Earth harbors extremophiles, or organisms that can survive in extremes of heat, cold, poisonous (to us) chemicals, and even in vacuum. We've found creatures who live without oxygen around the edges of super-heated volcanic vents at the bottom of the ocean, and we've found life in the brackish pools of the high Andes, as well as the ice-covered lakes of the arctic. There are even tiny creatures called tardigrades that can survive in the vacuum of space. So we have direct evidence that life can thrive in pockets of alien atmosphere on Earth. In other words, we know life can survive in conditions we've seen on other planets and moons. We just haven't found it yet.
Sign of other life forms
This show there might be other lifeforms out there.
In recent years, the Mars Express Orbiter detected methane in the Martian atmosphere. Methane is a gas frequently produced by living things, though it can also form inorganically. The gamma ray spectrometer aboard the Mars Odyssey Orbiter detected a significant amount of hydrogen in the top few feet of the surface of Mars, a likely indication of abundant ice. The famous rovers Spirit and Opportunity produced conclusive evidence that liquid water once existed on the Martian surface. This latter point is confirmation of what we have known for decades--photographs from orbiting spacecraft had shown numerous features that are best interpreted as there having been much liquid water on Mars in the past. This would require Mars to have once had a much more substantial atmosphere than now, an atmosphere that provided enough pressure and warmth to sustain liquid water.
This has exciting possibilities for creationists. First, secular scientists have concluded that Mars, a planet with no liquid water, once experienced a near global flood, all the while denying that such a thing could happen on earth, a planet with abundant water. Second, many creationists think that the earth's atmosphere underwent tremendous change at the time of the Flood. Obviously, at least one other planet did experience a catastrophic change in its atmosphere as well.
Life on mars
There was great excitement in the media when a group of scientists from NASA announced they had found evidence of life on Mars. Their evidence, an alleged Martian meteorite, was vaulted to center stage, and everyone from CNN to Night-line ran special programs with interviews and video footage of the scientists and their prized specimen. President Clinton was so excited by the announcement that he praised the U.S. space program and took the opportunity to establish a bipartisan space summit headed up by Vice President Al Gore to study the future of U.S. space research.
What I think
I think there is life on other planets an not because of things off the internet but I did do some research on websites like NASA and other science websites.NASA's scientists said that they found life on Mar. If you look at the pictures on video you might see proof that there might be lifeforms out there that we don't know about. Maybe everything doesn't need water or oxygen to survive after all.If there is others there extraterrestrials.
