The Sun, a star formed about 4.6 billion years ago, predates Earth’s formation. It originated from a cloud of gas and dust, undergoing nuclear fusion to produce energy. Meanwhile, water molecules on Earth have existed for billions of years, likely arriving on the planet through various cosmic processes like icy comets or asteroids colliding with the young Earth. Some studies suggest water’s presence on our planet dates back to its early formation, possibly within the first few hundred million years. Therefore, while the Sun’s formation preceded Earth’s, the water currently present on our planet might indeed be older, having arrived from celestial sources during Earth’s early evolution.

When we touch something, it feels as though we are making direct contact, but at the atomic level, this isn’t the case. Atoms are composed of a dense nucleus surrounded by a cloud of electrons, and it is the electrons that play a key role in preventing true contact. Electrons carry a negative charge, and when two objects come close, the electrons from the atoms in both objects repel each other due to electromagnetic forces. This repulsion is incredibly strong, preventing the atoms from ever actually meeting.
