[The Matrix] What aspect of Neo’s life in the Matrix made Morpheus suspect that Neo was The One? His hacking ability? His physical resemblance to the first man to free them?

morpheus says when the mayrix was built there was a man born inside who could edit the matrix.   did mr anderson look like that man?  

why did morpheus think neo was the one?

Cypher told Neo that Morpheus claimed 5 others were The One before Mr.Anderson was discovered. All five of them were hyped up as being the hero, tried to take on an Agent, and the expected happened.

In original cuts of the script of the story it was made even more clear with Morpheus flat out admitting he just claims people be beleived are chosen. Morpheus is a being almost entirely running on belief.
