Why Don't We Search for Different Life?

Well ... <a href="http://www.theregister.co.uk/2015/02/28/saturn_titan_azotosome_life_not_as_we_know_it/" rel="nofollow noopener" target="_blank">http://www.theregister.co.uk/2015/02/28/saturn_titan_azotosome_life_not_as_we_know_it/</a> Is this when astrobiology ceases to be sci-fi and becomes science?

I have always been fond of Asimov's "Not As We Know It - The Chemistry of Life" <a href="http://www.bigear.org/CSMO/HTML/CS09/cs09p05.htm" rel="nofollow noopener" target="_blank">http://www.bigear.org/CSMO/HTML/CS09/cs09p05.htm</a> The how is always the most difficult part of it Besides sending out probes, they would have to have fairly advanced sets of laboratory experiments built into the device, but i would think that a possible "mother probe" with "subordinate" probes for collection that would collect data and materials... as certain types of physical collection would take different times and different types of probes, the different searches would be concentrated into the most logical spots which would be found by the mother probe... the mother would also have to have the ability to collect physical material and manufacture new "subordinates", fix itself and even replicate the whole sheebang to proceed further into space as the initial probe stopped at point A to investigate.... almost seeding the galaxy with replica's searching for life in an ongoing investigation We may want to consider designing the probes with advanced AI that could learn as well, that way the mother probe could also learn as it went along and develop better search possibilities or even advance the detection and analysis possibilities of the equipment This may also mean advancing the search of the galaxy as well as knowledge, as the AI would learn at it's own rate, not hampered by our similar biological constraints and then perhaps it would also learn certain secrets of physics and the universe that would benefit biological life all speculation, but that would be my starting point. IMHO - it would be easier to design self replicating and self fixing probes to search out our solar system, then spread elsewhere then it would be to develop the tech to take our species into space, considering the hazards, and spread in a colonization process. The radiation hazard alone would suck, but then we would have to mess with everything from micrometeorites speeding into the craft to the hazards of taking everything in a self contained unit with incredible mass... of course, all of that mass would have to be able to move while protecting the biological organisms in it...so it would seem that it would be FAR easier to just design a series of probes But i am just speculating, mind you i am sure that the real pro's have already taken all that into consideration BUT... if they DO want to send people to investigate I AM VOLUNTEERING TO GO

Why don't you search for alternate theories of the universe instead?
