CARBON!
As of now, no non carbon-based life forms have been found on Earth. All known life on Earth is carbon-based.
earth and life is carbon based
All life on earth is "Carbon based"; meaning they are composed of Hydrocarbons.
a man life on earth is basically based on his immunity.
There is limited evidence to support the possibility of non-carbon based life on Earth. Some scientists have suggested that alternative biochemistries, such as silicon-based life forms, could potentially exist in extreme environments where carbon-based life may not survive. However, no definitive proof of non-carbon based life on Earth has been found.
While carbon-based life forms are the most common on Earth, it is theoretically possible for non carbon-based life forms to exist. However, there is currently no evidence of such life forms on our planet.
All life on Earth is carbon based, including bugs.
No, they are carbon-based as is all life on earth (as we know it). They do have silica as part of their body, but the main part is carbon.

Respect for Earth and all forms of life
No. There is no real reason why extraterrestrial life should be the same as Earth life. It might be based on a completely different chemistry, for instance.
The significance of Earth's atmosphere is the sustainment of land based life.
