How do you know with certainty that a file has been created in Word format by a certain person and then converted into a .pdf file?

I need to check the .pdf files, which - by the format not so well edited - look like converted Word files myself.

How can I find out who created them in Word?

Under properties - author, I see the name of the person. Does this prove that they created the file in Word originally?

Nothing can be proven with forensics PDF unless a document has a digital signature, or an approved authority in a trusted repository.

To put it more simply: No. Anyone could change that name with Acrobat or other tools.
