Does making a statement like for example "Mermaids don't exist"

I actually saw a mermaid once when I was high as a kite at Malaga Cove near where I live in Redondo Beach. We had been drinking and smoking weed at the beach at night. Then we were running along the shoreline jumping over clumps of seaweed. We both jumped over one clump and we both stopped simultaneously in our tracks. There was what appeared to be a naked lady entangled in kelp, or part kelp, or part sea creature. We both saw it independent of one another. We slowly crept back to make sure our eyes had not deceived us. And we both ran in terror because that is indeed exactly what we both saw, a dead mermaid. The next day I checked the morning paper and there was no report of anything unusual on the shoreline at Malaga Cove. But we know what we saw.
