# How and when was the $\mathsf{CO_2}$ scrubbed when Earth was still primordial?

How and when was the $$\mathsf{CO_2}$$ removed in primordial Earth atmosphere? What is the main mechanism of this removal of $$\mathsf{CO_2}$$? Is it dissolving in water? Or rock weathering? Or was the bulk of $$\mathsf{CO_2}$$ actually removed by early life?
