Within the Statistics tab in File/Properties it shows a Created date. Is this date 100% accurate as to when the document was first created?

I'm pretty sure it is and am trying to find some official Microsoft documentation to support it but I'm really struggling. I can't find anything on the Microsft website or in Word bible books.

Has anyone seen any documentation on this? If so, I'd really appreciate something giving me a link.

Apologies if this is posted in the wrong forum, wasn't sure which one to post in!
