We know that there might have been life on Mars, but could Mars have been responsible for the beginning of life on Earth, if new evidence is to be believed. Professor Steven Benner, a geochemist at the Westheimer Institute for Science and Technology, has posited that Martian meteorites thrown by volcanoes or impacts may have landed on Earth and acted as “seeds.” He argues that the oxidized mineral form of molybdenum, a building block necessary for life to grow, wasn’t present on Earth due to low oxygen levels three billion years ago. However, it was found on Mars, which had oxygen at one point. Meteorites carrying the element could have crashed on Earth, bringing the ingredient that may have helped tar form, which led to the first organisms. It’s an interesting thought, because if so, we could technically be part-Martian!
