Basically, being human beings (from planet earth), may be we are trying to look for which we cannot even perceive. Is it one of those cases when we search for something with a preconcieved notion (that it looks like this or have this kind of molecules etc), so even though that thing is right there in front of us, we just cannot notice it ?
Any views ?

This gets at the definition of "life".
In order for humans to recognize something as "alive" the thing must fulfill certain criteria. The preconceived notion is implicit in the definition, since humans come to the analysis with those criteria in hand.
In your scenario, where does the ultimate definition of "life" reside? If it resides with biologists, then the thing must possess the accepted criteria. A total incomprehensibility means that humans would NEVER be able to "preceive" as you say, and so, from the point of human science the question is moot, since you have defined the issue as unknowable.
If you mean that someday, based on new knowledge or theory, humans might be able to perceive, then, at that point the additional knowledge would become part of the list of criteria, and so, by definition would be included in the "preconceived" notions. This situation appears to be outside your scenario.

we have 91 natural elements on earth right? OK, it is then safe to presume that these 91 elements that we know understand and perceive are all over the universe since at the moment of the big bang all matter spread in all directions. there might be other elements (there is a high probability that there are) in the universe that we on earth do not have. These 91 elements are the building blocks of all life on our planet. Mars is so close to us in cosmic terms that the odds of life existing on Mars that we cannot perceive are slim to none. Why? Because since Mars is so close, all 91 elements can either exist on Mars or be created on Mars (like water generates atmosphere, such a chain of events) So, if we have on Mars the 91 element we know and perceive...how can there inperceivable life exist if we do perceive the life forms' building blocks? On another planet, much further away this premises could be true but so close...the chances are mot likely none.

you're on target, i imagine, because from the starting up, scientists were searching for life in accordance to what they study life examples the following on earth. we must have an oxygen depending surroundings to stay. really, it really is been elementary that the way we procedure oxygen is particularly unique because that we had to make some radical physiological adjustments only with a view to respire. who's to assert what may have advanced "accessible" that doesn't require oxygen in any respect, particularly, their lifeform calls for ammonia-wealthy atmospheres to be sure that them to live to inform the tale. it may bypass adverse to each and each and every of the guidelines of technology that those lifeforms exist, yet on the grand scale of issues, there confident sounds like the opportunities may be in opt for of them present someplace.

It is potentially possible. I think it is possible that there are microscopic organisms that have evaded us, but nothing big.
