Answer:

The existence of electrons was not something he set out to prove, but a conclusion of his experiment.

Cathode rays were unexplained phenomena and Thomson was investigating them. By determining that there was a constant charge to mass ratio, he deduced that it must comprise of identical particles which became known as electrons.

Hence the existence of electrons was not something he set out to prove, but a conclusion of his experiment.
