Barring birth defects and genetic oddities people come out with a range of highly predictable physical and mental attributes. AKA “equal”.

The writers of the Declaration were not talking about equality of physical and mental attributes. They were asserting as self-evident truth equality of God-given, and therefore unalienable, rights.

They were religious, so their writing was bent that way. But the concept holds just fine without religion. As I pointed out, there is self evident SCIENCE of our basic equality, and our basic actions and reactions.
