I think I saw Bigfoot?

I live in Fl near Port Charlotte and I was in a swamp buggy with my Dad, brother, and uncle and I looked over to my right and I seen a big black animal and it was really hairy it was pretty far away and it looked like maybe 7 or 8 ft tall so I hit my brother and he looked and he saw it but when I tried to get my uncle and dad it ran and they didn't see it. They laughed at me and said im full of sh*t. I'm pretty shure it was bigfoot because it was to big to be anything else I tried getting a video of it but it was gone. I sware i'm not lying! Could it have ben Bigfoot??
