She resembles the sun.
We cannot live without her.
She alters her face every day.
We periodically see the same landscape over generations,
yet life is so short that no one can remember that.
He resembles the moon.
We rediscover him in each decade.
Only if she helps us can we see him.
He frequently changes his appearance not because he is evolving
but because we are revolving.
We call her nature.
We call him artifacts.
