First-grader's response to a "class puzzle" of the week "is so deep, adults are debating it on a Twitter thread that exceeds 2,000 Answers and 231,000 "likes."

Bret Turner, an elementary teacher from the San Francisco Bay Area, recently asked his first graders to solve a "puzzle of the week. "He said:" I am the beginning of everything, the end of everything. I am the beginning of eternity, the end of time and space. That I am? "

The answer is th The letter e, but one of Turner's students went much deeper.

" The first guess from one of my 1st graders was 'death'. and such deep, somber and reflective silence fell on the class that did not want to tell them that in reality the answer is the letter e, which just seemed so banal at the time, "Turner said in a tweet on Tuesday that has since returned viral.

He told USA TODAY that it is not unusual for his students to speak about death

"Little children talk about death all the time: grandparents, relatives, especially pets," he said. "It's fascinating to them, and also normal."

Twitter users had their own thoughts. One answer questioned how death is the beginning of everything (it received more than 145 responses), another said that the entelechy (connected with Aristotle's distinction between matter and form) seems relevant, and a few said that the obvious answer is God.

Turner, who teaches at Head-Royce School in Oakland, said other student conjectures include: Not everything, all things, the ending and "nothing".

Maybe these kids are ready for more challenging puzzles.

Perhaps the next unit will cover "The banality of buffering through Germanic and Nordic mythology," Turner joked.
