present continuous and present simple

We use present continuous only with actions like( running-walking-sweeping- eating- raining)but some verbs like( know-need-want-believe-remember-understand)are not actions so we must not use present continuous. we use present simple.so we can`t say I am knowing( this is wrong) we should say I know
