Revising the truth

Darwin said the appendix was a vestigial organ, a remnant of evolution that have no function whatsoever. Guess what? He's proven wrong! See here.
Everything has a purpose. Nothing is made just for the sake of making something. If we can't figure out the reason or purpose then it'd be because of our limited abilities and knowledge. We can't be lazy and just judge something we can't figure out as nothing. If it is there, it must mean something!

It's like building a machine without a manual. Trying to fit those sheets of steel there, a nat here, a bolt there, a pipe here. Then when it looks like something in the brochure, we weld it all together. When the machine is started, it works fine. Then, while using the machine suddenly a curious square peg was found. A piece of the machine was left out! But the machine works fine, and you could swear that there were no square holes in there, only round ones. Hmm...how? It is such a bother to figure out where that annoying piece go to fit in the machine and it doesn't effect the running of the machine..so it must be unnecessary, maybe something the manufacturers mistakenly gave you extra, for backup you know. They sometimes do these mistakes, hey, not everybody's perfect eh?
So you just ignore the square peg's existence as unimportant. And the machine works beautifully..... For awhile.
Suddenly all falls apart, the machine starts making funny sounds. Now you think it may be because of the square peg you left out. Asking the manufacturer, he told you that actually that peg is the most important piece of all, that is why it was so different from others and now you're not eligible for warranty because it was you who made it faulty in the first place. Need to buy a new one. Haha! Padan muka.
Try replacing the machine with the ultimate truth. The pieces of the machine are the bits and pieces of knowledge from various studies, observances and theories over the years. Trying to build the truth, we gather all these knowledge together to form a clearer picture. But when faced with something we can't figure out, we chucked it out as unimportant. So the picture of the 'truth' we worked on still could be used, it still worked for the problems faced at that time. However, over the years that 'truth' would be challenged in light of new studies. The old facts suddenly revealed themselves as fiction. Everything needs revision, everything have to be reconsidered in light of the new facts.

The lesson now is this: nothing is made for nothing. If it is there then there must be a reason. Be patient and never stop searching for the truth. Nothing is ever what they seem ;)
