Our Father is the Creator of the universe, Lord of lords and King of Heaven and He wants us to call out to Him. Actually, more than that - God wants to talk with us - have a regular conversation regularly. We formalize it by calling it prayer, but it’s how our relationship grows. It’s extremely important to God so it should be even more important to us.
God has stuff He wants to share with us. Deep wisdom, insight, understanding of things and situations that we have misunderstood, great and unsearchable things. Wow! How can we be too busy for this? How can we not nurture our love with God? Call to Him and listen...
