Awesome question!  The only way I can truthfully answer you is to tell you that faith in God / or to not have faith in God is just that, 'Faith'.  Faith there is/ Faith there isn't.. right?  It's a free-will decision we each have to make for ourselves and stand by it with complete conviction!

Do you know that even Darwin, (the king of science and evelution), before he died admitted that he believed in God?

This is what I tell anyone who asks me similure questions about my faith;..  "What do you have to lose in believing in a forgiving, loving, Heavenly Father who wants to reward His People with a Paradise Earth??  It's better to Believe and have the promise of His better day for us, than to not believe and have been wrong!"  (as we all know, by then, it will be too late to change our mind)
