Because you can’t see the truth.
Some of us who receive human bodies in this life are born with dignified appearance, and that is still related to the practice in past lives. As for why this life is like this, I can only say that it is a waste of skin.
Observe carefully, before the age of 40, a person's heart is really good, but after the age of 40, a person's appearance becomes more and more ugly as he gets older. Don't look at your appearance when you were young, it's only for a while. And everyone in China who knows physiognomy knows that what we call good-looking may, in the eyes of physiognomists, mean attracting a romantic partner, which is not a good thing!
What is the best photo? Of course it was a Buddha statue. It was because Ananda saw the Buddha's appearance that he wanted to become a monk and practice Buddhism. He believed that this was not given by his parents, but was a result of his practice. There are detailed instructions in the Shurangama Sutra, you can read it.
