There is no scientific proof that suggests we are all made of light. The statement "we are all made of light" is not a scientifically supported claim.
Humans and other living organisms are composed of various elements, such as carbon, hydrogen, oxygen, nitrogen, and others. These elements combine to form molecules, which in turn make up the complex structures and substances found in our bodies. Light, on the other hand, is a form of electromagnetic radiation characterized by photons.
While light and matter are both governed by the laws of physics, they are fundamentally different entities. Light does not have mass or physical substance in the same way that matter does. It interacts with matter through processes like absorption, reflection, and emission, but it is not accurate to say that we are made of light.
It's important to approach scientific claims with critical thinking and rely on empirical evidence and rigorous research to support any assertions. At present, there is no scientific basis or evidence to support the notion that humans or any living organisms are made of light.
