I’m curious
I have been thinking about something on and off for awhile and was wondering if someone could help. It has to do with all the undocumented people who are entering our country, mostly across our southern border with what it looks like with nothing more than the clothes they are wearing. How do they travel so far without the means to take shelter at night, eat drink and take care of their bodies needs?
How did the person who invented the first clock know what time it was?
