I need help in choosing the correct tense or structure for this idea I'm trying to convey. I came up with the first sentence below, but then I thought of the other two sentences and found myself confused.
Our parents and ancestors had began this practice a long time ago.
Our parents and ancestors had began practicing this a long time ago.
Our parents and ancestors began this practice a long time ago.
In the above sentence, 'this practice' refers to upcycling.
I have consulted grammarly, ludwig.guru and searched for news article containing similar sentence structures such as this one, but I'm still not sure which one I should go with. I would appreciate any help that can point me in the right direction. Thank you.
