Yes, we can get through life by ourselves without God, and without His help.
But the converse is also true, we can get through life with God’s help and support.
So why should we choose to believe in God and live our life with Him rather than without Him?
God made each one of us as individuals, and He planned our whole life out for us before we were even born. Therefore if we believe in God and let Him guide us through life, surely we will achieve all we can in life, as God knows and understand us and our abilities.
