Buddha taught non-self (Anatta) which is one of the three characteristics of existence more than 2500 years ago.
Everything constantly changes, we can't arrest aging process, we can't take full control of our emotions and also nothing is permanent hence it's non-self.
Even neuroscience has proven Buddha's theory of non-self which the Buddha self realized himself and he shared this knowledge with his disciples and lay people.
"This is not myself, this is not mine and this is not what I am. There's no 'l'. "
