Life on other planets?

After reading articles in New Scientist, it made me wonder that maybe there was life on other planets. Afterall, they may be older than us so we have never had the chance of meeting a Martian.
Presence of water is the indicator that life may once be present on Mars surface. Or they may live in the soil. Who knows? So exciting. Scientists also claim that rocks may contain some fossils of life. Wait until they collect the rocks from Mars and trying to do an Indiana Jones on Mars. Isn't that exciting? Next time, NASA will send a maned mission to Mars so we don't have to watch movies about going to Mars anymore.
Isn't there a book somewhere called: Men are from Mars? Who knows if it's true or not. If Mars was once habitable, then we may come from there. Maybe not. No one can dispute that life may come from outer space, so why not Mars?
I suppose people will think me crazy, but before we have enough evidence otherwise, we can let out imagination run wild.
Wish they can collect more data in the future so we know more about the red planet. The results may show there wasn't any life on Mars, but who cares, let's find out more about Mars. We can learn from the atmosphere and the soil of Mars about the past and the future of Earth. We can learn about whether organisms will or will not be able to adapt to such harsh environment. We can look at the soil and try to solve the puzzle of Mars's history. We can also find minerals and other resources on Mars so one day we can live there.
Dreams are just dreams when you are thinking them, but it will become reality if you follow a logic path to solve the problems. Hope they success!
