"Your so called evolutionary theory is just a hypothesis"
Mostly True. It is a Theory, but not a Law.
"there are no evidence that supports it."
Leaving the grammatical errors aside, there is significant evidence to support the ToE. However, I personally believe that it leaves several questions unanswered also, and should be critically-re-examined on an ongoing basis.
"Consider the bacteria, despite all the experiments in the Lab, no has seen bacteria evolve into anything other than bacteria."
The ToE does not state a timeframe - and all available evidence indicates a typical timeframe in the ultiple eons for even minor changes and divergings.
"Some scientists even say that bacteria is the most fit organism on the planet."
Citation needed.
"If that is true why would bacteria need to evolve to lesser fit organism?"
Why are humans the one species with the ability to shape the planet to their will? We are specialised. So long as conditions which suit them exist, the specialised creatures will out-compete generalists.
