if a lion could talk... we'd probably get the gist

The fact of difference - biologically, existentially - is not trivial, but difference ultimately reduces to similarity.

The human perspective is a subset of the mammalian perspective, shared with the lion.
Mammalian perspective is a subset of sentient perspective; sentient perspective is a subset of the (theoretical but readily conceivable) perspective of all living things, which is a small subset of (the proposed) 'true' cosmic perspective - but a subset so infinitesimally small, and specialised, as to be of no use as a pointer to the whole.

Cosmic perspective is by definition unknowable: it is, so to speak, 'the mind of God': another reason why the concept of an anthropomorphic deity is so unsound.

If nothing more, the lion and we could intelligibly swap ignorance stories.
