As a child, I was afraid of death and wanted to live forever, but after growing up and realizing the meaning of life I do not want immortality. It will be terribly boring and painful. I will not be able to find interesting activities, because I will try everything and life will lose its meaning.
Agree with you. We just need to release space for new generation. It is a cycle of life. And life on Earth is just a first step as there are many of them yet to come.
