A „purpose“ requires a creator or thinker to set the goal or purpose. From my experience sometimes women have this view. I think this is a ditthi. As per Buddha Dhamma all happens because there are causes which lead to results if conditions are good enough.
There is also a common view in Christian communities, that we all have to come back to our Father (God) and we are now as a human being in search to fulfill this purpose. This is also a ditthi which does not take into account the animal realm. If you ask a Christian believer: What type of beings are animals? Do they also have a “soul”, feelings, perceptions …? They will hardly understand your question and what do you want. The world view of the Buddha is missing.
