Why is scientific thinking so important?

Though there are many flaws within scientific thinking (here is one of them)What is Real?

So, if you read the philosophical problem in "what is real?" you see one of the problems of scientific thinking because the homeless man wasn't killed, there was no hit and run because no one saw it happen.

I also have this problem every time I walk through the forest knowing that scientifically I cannot prove that trees fall down even though I know they do, without putting a time lapse camera up to demonstrate that they fall down eventually. I find that science being this Frail is kind of ridiculous. So, I might have to wait a year or more to demonstrate to people scientifically that trees fall down even though we all know they do in the wind or for other reasons. So, how can I completely take science seriously because of this truth?

And how much is lost that is vital information because of this insistence by scientists around the world.

And will we eventually even go extinct one day because of this philosophical problem from the time of Plato and Aristotle?

But, still given all that scientific thought is important because otherwise we still would be doing things like bloodletting to let the evil out of our bodies and things like that.

However, there has got to be a better system than: "When a tree falls in  a forest did it happen if no one saw it? The philosophical an scientific answer is: "No!"

In my system of moving scientifically forward that I use only for myself and anyone else who listens is: "IF I can sufficiently prove something to myself what else do I need to stake my life on that truth?"

(especially if I don't have to convince anyone else of it because I'm a free thinker and capable of rational critical thought like a College student should or beyond that.)
