Implication #1: We can trace the origin of all the cells in our body back to the first cell; the zygote produced by the fertilization of a sperm and egg.
Implication #2: The origins of all cells can be traced back through billions of years of evolution to "LUCA" the last universal common ancestor of all life on Earth.
Implication #3: There must have been a first cell that arose from non-living material.

Boiled water evaporates and moves into the larger flask, where it combines with methane, ammonia and hydrogen gases in a large flask.
Sparks are fired between electrodes to simulate lightning.
A cooling condenser turns steam back into liquid water, which drips down into the trap, where organic molecules produced in the reactions also settle.
