Why we cannot understand Quantum Physics.

The problem is that physicists draw the Quantum Physics
with ‘ math point-particle’ and therefore they ‘kill the picture
of ultimate reality.’
Of course, physicists know very well that the particle isn’t a
math point, but any another model of particle brought difficult
which they could not solve. Therefore physicists preferred
to think about particle as a structureless point
===.
At last from 1968 physicists decided that instead of a
‘point particle’ they will use ‘a string – particle’ and developed
‘ string theory’. The problem is that there are 5 or 6 ‘ string
theories’ in 10 or 11 dimensions .One theory is better than
other one. And they decided to unite them in one
‘ M-string theory’ . This theory is still in a cultivation.

So, now we don’t know what elementary particle is and
therefore we don’t have the Philosophy of Physics.

Is my opinion difficult to understand , is it ‘an unintelligent garbage’ ?
