Yes, there is a need to pray. However, understanding that we are limited in ability and capacity, and the spirit controls the physical, many life issues are beyond the natural realm; it is wisdom to acknowledge the need to make prayer pivot in our lives.
Also, knowing that there is a higher force, all-knowing, all-seeing, and almighty, will help to give meaning to our life and existence.
If we quickly scan our world today, we will observe that all that exists are bowing to some force. Systems and patterns characterize almost every form of existence. Seeing that we are not primarily responsible for them, it is only wise to recourse to the one who initiated their existence.
