Watson and Crick to ways to learn about other intelligent life. Are we really made of the same stardust?

Did Watson and Crick knew the power of their simple invention - the structure of DNA - our building blocks, our gene program and genetic information. What followed after their one page publish on the structure of DNA - double helix encoding information using four nucleotides - A, T, C, G, is numerous of new advancements in the field of biology, biochemistry, evolution and nanotechnology, as well as in genetic engineering, research and finding the causes to other genetically inherited or epigenetically modifications. DNA can also store vast amounts of digital information with high density and durability. Experiments have encoded books, videos, and other data into synthetic DNA molecules.

Looking at bigger scale, do the way we operate is similar to the way other organisms and intelligent beings in the outer solar system function? Are we made not only of the same elements- hydrogen, nitrogen, oxygen, carbon, phosphorus which have been universal because they were forget in the inner reactions and how stars are born,  but are we made of the same building blocks and the way babies grow and life begins? Even if it might be based on similar building blocks, most probably the exact biochemical structures differ.

Our shared chemical and physical makeup gives us a potential common ground with extraterrestrial intelligences:

   - Chemical Universality: The periodic table applies universally, so the biochemistry of alien life may involve familiar elements.

   - Physics as a Common Language: The laws of physics are constant, offering a basis for universal communication (f.e. radio waves, mathematical concepts).

   - Information Encoding: DNA-like molecules or alternative information-storage methods could emerge wherever life exists. If we ever find extraterrestrial life, comparing genetic or molecular information could be a starting point for understanding their biology.

This interesting and important question and answer could give us explanation of whether we are something special and more complex and of higher order, or are there other beings like us and how far have they reached in their development.

The interconnectedness we allude to is profound. Our biology reflects the universal processes of chemistry and physics, which means the search for intelligent life elsewhere involves looking for variations on the same themes that enabled life here. Whether through shared elements or convergent mechanisms of learning and communication, the way our organisms work might hold clues to connecting with other intelligent beings.
