Silicon is the element that is similar to carbon in its structure and may form a basis for life elsewhere. Silicon can form long chains similar to carbon, and some scientists speculate that silicon-based life forms may exist in environments where carbon is not available. However, it is important to note that there is currently no evidence of extraterrestrial life, whether based on carbon, silicon, or any other element.
