4. Earth is older than we thought
All the timeline statistics that we knew regarding the earth are actually wrong. As it turns out, life on Earth started out a billion years earlier than we expected. There is a whole theory and proof apparently that stated, life took a longer time to fully develop. This means, during the early years of Earth when it was nothing but a toxic wasteland, life was slowly forming. This can mean one thing, the planets we called non-habitats can have life forming in them as well, it’s just taking longer to fully mature like it did on Earth.
