With the very first "animation" from the primordial soup occurring some 3-4B years ago, would it not be an ongoing process of not just lineage but of completely new "stuff" appearing in a pond near you? If not, then why not?
Life is believed to have evolved 3-4 billion years ago deep in the oceans near volcanic vents. This is often referred to as the "primordial soup" from where the first cell formed.
Answer and Explanation:
The conditions on Earth were vastly different 3-4 billion years ago than they are now. Back then there was a lot more methane, ammonia and hydrogen present. There wasn't nearly as much oxygen present as it is now. The conditions were conducive for the first cell to come about. (Urey and Miller recreated these conditions in the lab and were able to make amino acids. Amino acids are critical to life).
Furthermore, perhaps there is tinier, new life being created somewhere on Earth (or somewhere in the solar system). That is not beyond the realm of possibility. The only unfortunate aspect to that is that the Earth now is filled with lots of creatures and there is a likelihood that that new life in a pond near you might get eaten up
