Well coming the religion and spirituality, you wanted to know if God exists? Not c'is a shadow of a doubt, God exists, and reveals himself to all those who believe in him and seek him through their prayers!
Here is what he has said God:
Call upon me, and I will answer thee, and shew thee great and mighty things, which thou knowest not.”
14 Make thankfulness your sacrifice to God,
and keep the vows you made to the Most High.
15 Then call on me when you are in trouble,
and I will rescue you,
and you will give me glory.”
