Atheism the unscientific belief (part one, two, and three)

[robvalue]

C'mon now, we're so close! How can we be sure we've removed our own bias, mistakes or even incompetence from the conclusion we think we've drawn?

Everything in this universe is temporary.
What make sense today tomorrow will be discarded in the rubbish bin of history so what we think it is perfect today will be found
wrong tomorrow.
Physical science can not possibly found permanent solution to the main human problem which is to find permanent peace of mind but by 
following mother nature way of acting it is possible to find solutions to a lot of material-physical-mental problems.
Now let me give an example of bias and incompetence and the arrogance in refusing to follow mother nature example.
By using a tiny bit of intellect we can draw the conclusion that cells must be alive in order to deliver us the nutrients.
Dead substances are not able to feed us so we would be dead by now or as a matter of fact never existed.
If cells are alive then we can easy deduce that the cells got to be conscious.
As the small merge in the big by nature we can also deduce that the cells consciousness merge in us.
From here we can also deduce that the cycle of merging goes on and on leading to some goal.
Atheism is therefore full of arrogance into believing that the cycle end without a goal.
Why the cycle of merging into something big should end all of a sudden when in fact mother nature show us that 
the cycle goes on and on? 

None of that answered my question. Want to try again? You've been working on something, and come to conclusions. What can you do to minimize your own bias and errors? This has nothing to do with atheism, so it's irrelevant to randomly slag it off. But by all means do it again.
