The basic building blocks of life are [[protein]]s, [[carbohydrate]]s, [[lipid]]s, [[nucleic acid]]s and [[amino acid]]s. These organic compounds are made up of chemical elements like [[carbon]], [[nitrogen]], [[oxygen]] and [[hydrogen]]. It is believed that these elements constitute the essential elements to form life. But the elements that should have formed such organic molecules must have been inorganic. One of the key inorganic compounds that should have enabled the formation of the organic compounds is the [[water]]. The Miller–Urey experiment clearly showed that this is plausible as the experiment used inorganic materials as water and gas with electric discharge to create an aggregation of amino acids called [[coacervate]]s. | The basic building blocks of life are [[protein]]s, [[carbohydrate]]s, [[lipid]]s, [[nucleic acid]]s and [[amino acid]]s.

| − | + | === Why is abiogenesis not happening today? === | |
| − | + | It is believed that abiogenesis should have happened during a time on Earth, where the conditions were favourable for inorganic compounds to form organic compounds. The environment of the primordial earth was completely different from what we have today. Also, it could have taken millions of years and different geological and chemical processes for it to happen. In the current Earth, it is highly unlikely that we will be able to witness such an event naturally. | |

The closest we ever achieved to create abiogenesis artificially is in experiments like Miller–Urey experiment, where simple organic molecules are created. It is unsure if we will ever be able to create complex organic molecule structures out of inorganic compounds under artificial conditions. | The closest we ever achieved to create abiogenesis artificially is in experiments like Miller–Urey experiment, where simple organic molecules are created.
