Excuse me, I have a question

A few days ago my brother and I were in a loud argument on "the meaning of life". He says that he would like to be immortal, so that he can find the meaning of life. He belives that the only reason man hasn't discovere the meaning of life is because no one has lived long enough. I say that it doesn't matter how long you live because there is a scientific answer to the question "What is the meaning of life?". Isn't it clear? There is no meaning of life. All living things are the way they are because of mutation in genetics and the position of the earth from the sun. "Earth and sun?" The only reason bacteria was able to spawn is because of meteors that have pounded the earth in it's earlier years. These meteors brought with them germs and such, and with proper temperature and humidity and water and things life was born. Gee Patrick you really have to live fo 263 years to figure that out. Redwoods live for hundreds of years, go ask for their opinions. Please post your opinion on this topic and if you have a blog or site post it too, I would like to visit.
