If we define ‘Life’ in our modern terms as being restricted to Forms…then yes, life on Earth began, and it will end.
However, Sentience, in the way the Buddha defined it, is not restricted to the aggregate of Form. Sentient Beings ‘exist’ based on craving…they cannot be ‘destroyed’.
Only when the factor of Ignorance is replaced by Wisdom is the idea of a sentient being seen for what it is… a lump of foam, a magic trick… It never really existed in the first place, did it?
