When will we find aliens?

Chris Mckay, thought that he had found life in Mars, but it failed, but he didn't give up and still fighting to find life, but since then he hasn't found any evidence. Mckay and his team are investigating the planets of the solar system and think is possible to find life. Scientists say the most exciting kind of life would be the intelligent one. During next years scientists will continue improving the tools to be able to find live in the slar system and further from the solar system.

Opinion

I think there's life out of our planet, but with life, I don't think about ET like us, I think there are some microorganisms and also bigger ones like insects and things like that. They haven't been found because is really difficult to do it, and the technology has to evolve a lot, however life will be found in not much years, but finding aliens will be more difficult. In my opinion aliens will be found one day or another.
