OpenOffice doesn't open ebooks. They are a read-only format for PDF readers.

Please add your Oo version and OS to your signature from the User Control Panel, then you don't need to tell us every time.

I'm not sure what you mean by adding oo and os to signature. I created this ebook with openoffice why can't I edit what I created with the same program.

See my signature. From the User Control Panel link, you can edit your User Profile and Signature. Just add some simple formatted text showing your OpenOffice version and Operating System. I have also added some useful links to my signature, but you just need something like what I have in the last line.

I created this ebook with openoffice why can't I edit what I created with the same program.

You can. You can edit the original OpenOffice document that you used to create the Ebook.
By Ebook, I presume that you mean a PDF file. To open PDF files for editing you need the full version of Adobe Acrobat (not just the free Adobe Reader).
