Wearing a robe or uniform doesn’t make you a good person. Being a good person makes you a good person.
Just because you don’t know the reason for something doesn’t mean there is no reason for it, or that any of the possible reasons you can imagine are true.
Even to think is to suffer. Thought requires effort, energy, struggle, etc. Not to suffer is not to do anything — even to think or feel.
“What is there to see in this vile body? He who sees Dhamma … sees me…” (Samyutta Nikaya, 22.87).
There seems to be is an inherent contradiction between Buddhist monks’/nuns’ needing a body in order to meditate enough to become enlightened but not wanting to be (re)born, have sex or children, have possessions, kill for food, fight in the military, etc. They need to be here (because humans have sufficient intellectual complexity to understand their existential predicament and how to fix it), but they don’t want to be here. They have to use humanity, in other words, to serve their purpose, but they don’t actually like/want human life very much.
Poor countries often have poor waste management, water and air treatment, and power generation facilities. Even in large cities, people in Asia, Africa, Central and South America, etc. often burn their trash right beside their homes, bury toilet waste in pits beside their homes that may rarely or never get cleaned, don’t have very clean drinking water, and go without electricity every few days or weeks. A really good, humanitarian, and probably profitable idea for a large corporation, wealthy person, or the UN might be to build municipal utility facilities (water treatment; recycling; industrial quality incineration; urban air filtration; and solar, wind, or hydro power generation) into a fleet of ships that get deployed to the ocean and river shores of these countries — providing good quality utility services to a large portion of the planet at a cheap bulk rate.
Words like “best,” “top,” etc. usually indicate a subjective judgment. If something is the best, it’s usually just the best in someone’s opinion, not necessarily the most accurate, precise, etc. according to some objective measure. If no objective measure is given (e.g., if they don’t say something like “that sports star is the best in terms of points scored in one game”), I assume that it’s just someone’s opinion, and I suspect that they have some agenda behind calling it the best (e.g., they’re selling something).
Did God make all humans on Earth, or only the humans in your country or ethnic group?
