Greencard for father-no birth certificate

[vbsathya]

I'm planning to apply green card for my father. One of the required documents for I-485 is birth certificate of my father. My father does not have a birth certificate and he was born before 1970. Can we use my father's school certificate in place of birth certificate? Do we need to get Non-availability of birth certificate from local authorities and also get an affidavit from a relative/friend who is older than him? He is 74 years old and we don't have anyone who is older to provide affidavit.

In addition to a non-availability certificate, the following  documents can be accepted as secondary evidence:"
