I am because i think

What is thinking? its the most complicated physiological process ever. can lower organisms think? they can judge the circumstances and react .. but is it thinkin? if i react to a hot object (object), is that thinking? i guess not.. But then wot is thinking... i think wot lower organisms do is to percieve, not really think.. its a reflex which is formed due to completion of a circuit inside their brains (or neural ganglia as my sister tells me).. so its not thinking..

We are special beacuse we think !.. if u see, we also have networks of neurons an stuff like tht... may be our networks are more complicated... but they still are a physical phenomenon.. and thinking is a consequence of a higher complexity of neural networks.. but then wot makes humans think and not say chimpanzees?? their networks are somewhat lesser complex than ours.. but are they that less complex?? to make humans so unpredictable and them so predictable?? wot is it that really makes us think?? a few thousands of neurons?? then if that is possible, why do we have a choice at all to think or not to think.. monkeys dont have a choice... we do.. y??
