They actually could. They could climb walls, trees, etc. and not make a sound while doing it. I just hope you know that real ninjas do not exist anymore, but their styles do.

No. And I have been doing ninjutsu for 9 yrs. 6 in the bujinkan and 3 in AKBAN. It is nothing like the movies. The movies are all about being showy and fancy. Hollywood has so thoroughly distorted ninjutsu that even the art itself has become tarnished.

True ninjutsu is quick, brutal, precise, and most of all ruthless. We strike the throat and other vital areas. And we train specifically for that. We want to end a fight as quick as possible. We also fight dirty.

So no.

While the ninja are extremely adept at stealth (they can hide in the environment for days) the stunts you see in the movies are purely fictitious.

Just imagine Assassin's Creed, but 10 times better at everything.

of course not that is movie crap,granted they was like a cat ,but they could not jump 10 feet over a wall

The only way to know is to go back in time
