Heat disperses, Energy disperses - example hot cocoa becomes cooler

To collect back the energy also must use energy(disperse more energy) - example to heat back the cocoa u must use electricity(electricity is produced by dispersing energy - burning fossil fuel or the sun)

So in total the universe is dispersing energy until it become meaningless dispersed energy in empty space. (Cold death)

If u reverse this timeline u get will get the big bang - the universe starts out with the lowest entropy (highly arranged and efficient form, NOT random and messy) thus proving the existence of GOD..
