Do u believe in Prayers(Havans)

I believe in God and I do believe in the power of prayer. I have an incident where we were traveling across country. We prayed for safety and guidance. An hour outside of our destination our 6 month old went hysterical. We could not calm him down we pulled off the freeway. The second we did he camed down immediately. We took the opportunity to stretch for a few minutes. and got back in. About five minutes down the road we came across some stalling traffic. There was a car on fire, and two tipped over. One of the tipped over cars was a car we were traveling behind across the stateline. (no relation or anything) I think if we had kept on instead of pulling off that woud have been us too. A car was pulled over from being overheated and caught fire and something expoded causing the two cars passing by to be hit by the force. Nobody was seriously hurt just car damages. SO I believe in the power of prayer and Yes definately in God.
