Help! Water leak rear left side

Hi All, new poster and was wondering if anyone has had my problem.

I have pretty much ruled out a door vapor seal problem

A week ago after a few days of rain noticed the rear right side passenger floor was wet.

I poured a bottle of water this afternoon and pretty much ruled out a door vapor seal problem and I think my problem is from my door/door seals

It just rained so I went to check on my car and the pictures are attached from what I found

The seal on the body of the car is wet between the white lines, its not wet on the other side of the car and there are a few drops of water on my seat.

What is causing this problem? The seals on the body or door? any ideas would be appreciated
