Philosophical evidence of God

Hey guys. I have been thinking about evolution and our world. I think a really good arguement/evidence of God is purpose. I see that the process of evolution could be guided by God, or not, but what I mean is the purpose we see in life. A lot of people who do not believe in God think that our lives have no purpose. Whether that includes scientific observations or your own experiences, what tells you that life has meaning and purpose?
