What Do Zircones Tell Us About Life on Our Planet?

Zircons are a mineral that preserves chemistry from the time of its formation. They've told us a remarkable amount about our planet during its first 500 million years. And they have already provided us clues about what the surface of our planet was like at that time. If these zircons then can help us understand the chemical pathways that led to life starting on our own planet, is there perhaps scope for it to help us find life on others? I think we're at this amazing time in which humankind is searching for life on other planets. We don't know what the planetary conditions of our planet were like 4 billion years ago. And so that is really what we are after as part of
