Can’t find HOME page on the net

When I go and type in my website address my home pages is not there on the internet. A message is there that says,
Not Found
Sorry, but you are looking for something that isn’t here. You can search again by using this form…

I also can’t seem to find it on my edit page. All of my other pages are there if I need to edit them.

Can anyone please shed some light for me here.

Thank you in advance,
G
