Animals eat food to input energy and remain alive; it is fuel for existence. Animals don’t give thanks to God before eating though. Acknowledging the provisioning of God through his grace is a way humans with a soul differentiate themselves from thankless animals.
If original sin, or rather the punishment for original sin was waveform collapse into entanglement in the steady state of three-dimensions in the Higgs Field that is a state that requires the input of energy molecules to remain alive, in order for humans to merit salvation or rather receive salvation through the work of the Holy Spirit, Jesus Christ and the Father, they need to be spiritually awakened or reborn into the spirit. That is they have a spiritual dimension that did not exist when they were simply fallen animals.
Giving thanks to God before eating is a plain sign of being awoke in spirit.
