The Matter: Does it exist!

Couple of years back I guess 2 years back I watched a Documentory which talked about the Brain, Soul and matter.....and Quantum Physics from all big Prof. from top most Universities.

Let me share the thoughts....

How do we say or feel "The Matter".
The answer is simple by five sensors of humans...yea may be six if you are female :)
Eye, Ear, Nose, Touch & Tongue (Taste).
The answer above is incomplete....yes these sensors helps us for saying Matter exists but how.
The input from these sensors is converted into electrical signals which then goes into our brain and now brain interpret these signals to the existence of the Matter!

So if you are convince with this thought we can look for some experiments....
Suppose if take brain out and sends the electric signals similar to send by our eyes while seeing mountains, signal of tasty pastery and holding a toilet paper roll :P then what happens....
Our brain will assume that we are seeing mountains, eating a pastry while holding a toilet paper :) even if we are not actually seeing the mountains or holding anything. But due to these electric signals we can say we say "The Matter" exists.

So we can say or assume that nothing exists, it's just the interpretation by our brain of different electric signals....but yea one more thought....if there is no matter probably there is no brain which exists in real... this is also interpretation but by whom and how ?

This is the big question.....if nothing exists where these signals come from or send to or even interpreted by so called non- existence brain...

Many researchers at this points fails to answer the existence of "The Matter".
But there are few how goes into deep of this most confusing question and goes back to early history of humans to find out some results...
They landed up into some religious books....and they says nothing exists in the world except.. Yes except soul.

So nothing exists but only soul......but here after this kind of conclusion one thing came to my mind or disturbed me is that these researchers started everything based one a big assumption.....

Does brain really interpret these electric signals correctly? what if those signal interpretation is all wrong? what if there is some other mechanism by which we say "The Matter Exists".

For me currently it does Exists.....and I have my own reason of saying so....

What all you think ...and why so?
