When the Declaration of Independence says that unalienable rights are endowed by their creator it means those rights are blank?

When the Declaration of Independence states that unalienable rights are endowed by their creator, it means those rights are inherent and cannot be taken away or surrendered. They are considered fundamental to human existence and are granted by a higher authority, rather than by government or society. This assertion emphasizes the belief in the intrinsic dignity and worth of individuals.
