I accidentally permanently deleted all of my pages.

Hi. My name is John, and I recently started working with a theme on wordpress. For some reason, I moved all of my pages to the trash and then permanently deleted them (I don’t know why). The problem now is that no matter how many times I wipe my database, reinstall wordpress, and reinstall the theme, the pages just will not come back. All that shows is an about page. Is there any way to start completely from scratch? I have probably wiped my database and reinstalled wordpress dozens of times to no avail.
