How do I remove this stupid page?

I cannot get this gosh [moronic expletive] page off of my website, there isn’t anywhere to delete it. Everytime someone goes to https://www.Jeffsbestnutrition.com they’re going to see this idiot page saying “apologies, the” etc. instead of the page I set up to say homepage and it’s making my site look horrible.

Does anyone know how to get rid of this?

Honestly if it can’t work right out of the box, what freakin good is it? I chose wordpress because I have NO WEBDESIGN skills, and I don’t want to learn any.

If you know how to get rid of this please help.
