Could life have started without the presence of carbon on our planet? They say there are often many paths to the same destination - maybe this is true with life as well.
P.S. For those who aren't computer literate, AI stands for Artificial Intelligence.

You're not meant to answer your own questions are you? Oh well here goes...I've just found this link, which pretty much answers this one:

The conditions on Earth are such that life is carbon based. Some believe that life in other parts of the universe may not be carbon based. A good candidate element as a base of life elsewhere would be silicon. It is similar to carbonin many ways.

The generally held view is that elements such as silicon which have some similarities with carbon do not allow enough complex reactions for them to be substituted for carbon in any life form. The chemical "mechanism" for life is very complicated and requires an immeasurable amount of different chemical reactions as well as photoelectric and nuclear reactions that it seems only carbon can provide.

they are issues that would only be got here across after thousands of trials. and evidently, strict limit desires to be in position. in spite of the indisputable fact that, because the theory of technology is continually replacing using new discoveries, we prefer to really have sympathy to the drug employer besides. they don't look miracle makers, they only attempt to make salary by skill of promoting some thing that they "imagine" would help different human beings. imagine the international devoid of antibiotics and different drugs, what number of human beings would could die? If we agree that technology would get replaced, the drug employer would no longer have an excuse of increasing drugs expenses because of regulation healthy.also if we glance at the different section that has used the socialist equipment it has slowed down and did not stay as a lot as its Utopian promise. No equipment is appropriate yet open and loose marketplace is the perfect obtainable.

Carbon hydrogen oygen and nitrogen are the building blocks of all living things. an example is nucleic acid found in our DNA which every single organism has. nucleic acid has the four organic elements. because every organism has cells and all cells have DNA and DNA contains nucleic acid and nucleic acid has the element carbon all organisms are l made up of carbon.

sure it can

de designer used carbon
u can build them based not on carbon

well are carbon based things are organic, so I guess yes, you need the carbon
