Besides, the planet doesn't care about our little problems: https://www.youtube.com/watch?v=uHgJKrmbYfg
Same with the stock market, predictions about the house market, the weather, political events, and so on.

EDIT: As a recent example, consider the lies we were told by the administration about the effectiveness of surgical masks in preventing spread. While this lie was told in service of keeping the supply prioritized for health care workers, it caused vulnerable people to not wear them and discouraged people from wearing home made masks that might help prevent asymptomatic spread. We have only overcome this lie through public discussion and eventual acknowledgement by the CDC.
