seen vs saw

which is correctly used
i never saw that one
i never seen that one

I never saw that one.
I have never seen that one.

Both of Kitosdad’s answers are correct, Cintialovee.

Hi Cintialovee,

‘I have never seen’ is the logical use of the present perfect because it suggests here that up until the present you have not seen something. ‘I never saw’ is often used in conversational language but logically it doesn’t really fit with the idea that the past simple usually refers to a definite time in the past.
