Who said mermaids arent real?

Hi I know all of u probably don't believe in mermaids but I do!!! I do cause when I was 8 and I'm 10 now I saw one! OK I'll tell u the story,I was on a bit in Florida and I saw one it has brown hair and a yellow tail. And I know u guys r like she's lying but I clearly saw her as soon as she noticed I saw she she swam away so I believe in mermaid cause I saw one! So hope u guys vote and comment say the truth but im only ten don't be harsh!
