How did life on earth develope?
Below vv
Chemicals gave rise to amino acids, which in turn produced protein molecules, which somehow combined to form the first cell and mark the beginning of life on Earth.

The earliest life forms were probably single-celled organisms that evolved over time through natural selection and genetic mutations. Life on Earth most likely began around 3.5 to 4 billion years ago through a process known as abiogenesis, where simple organic molecules formed and eventually gave rise to more complex organisms. The exact mechanisms underlying this process are not fully understood, but key factors include the availability of water, the presence of organic molecules, and favorable environmental conditions.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
