As for scientific gratitude, which is the right to thank, it is to see a blessing from God, so if you see it from God, you have truly thanked Him

Ibn Majah narrated in his Sunan on the authority of the Messenger of God, may God bless him and grant him peace, that God revealed to Moses, “O Moses, thank me.” The right to be grateful. Moses said, “O Lord,” and whoever is able to do that said, “O Moses, if you see the blessing from me, then you have truly thanked Me.”

This is the condition of the one who sees the blessing, and from His blessing upon His servant is to enable him to give what he has of God’s blessings to those in need among His servants, so He gives them. In the hand of truth, not in His hand, they are watching.
