Can you prove that God exists?

How can you prove that God really does exist? Is He the Creator that Christians say He is or just an imagined up God that has not ever been there?  I believe that yes, we can prove that the Lord Almighty is a three in one person who lives, loves, and interacts with mankind. It does not come typically through rational thinking but through the evidence of everyday miracles that take place. Albert Einstien once said, "There are only two ways to live your life.  One is as though nothing is a miracle.  The other is as though everything is a miracle." Even if humanity sees the miracles of God on a daily basis they still will not believe. This was true for the Isrealites when they saw all of the signs and wonders on Mount Sinai, yet a whole generation died of unbelief. This is how it is today.  Let us broaden our self oriented minds and see the miracle in the small things. In Romans 1:20 it says, "For since the creation of the world God's invisible qualities - his eternal power and divine nature - have been clearly seen, being understood from what has been made, so that people are without excuse." I believe also that from the beginning of our lives we have a sense for God in our hearts. This is because Eccl. 3:11 says, "He has made everything beautiful in its time.  He has also set eternity in the human heart; yet no one can fathom what God has done from beginning to end." Not only is He omnipresent here in the whole universe, but He has left a mark in all of mankind and that is eternity. Every man longs for eternity, whether he knows this or not, but this is because it has been written on the human heart from the beginning. These are just a few ways we can see that God (Father, Son and Holy Spirit) really does exist. We just need to open our eyes.
