Is it normal to feel life has no purpose?

I felt that way for a while, but then I realized that all that religious garbage shoved down our throats doesn't matter. Whether there is an afterlife, or we just cease to exist, or something in between, what matters is the mark we make on the world we live in. Our children, our accomplishments, and our legacy. How we donate to the human race is the most important thing in any of our lives. No matter what anyone does with their life, they've donated by just living and experiencing the human condition.
