Well, there’s roughly 8 billion people on Earth, and the Wikipedia article for “human” says:
The average mass of an adult human is 59 kg (130 lb) for females and 77 kg (170 lb) for males.
Male vs female is roughly 50/50 IIRC. Ignoring distribution of adults vs kids for simplicity, then roughly 4 billion times 59kg + 4 billion times 77kg = 544 billion kg or 1.2 trillion pounds, if I did my math right.
Humans have a total biomass of 3.9×10^11 kg. Let’s assume our titan is magically immune to collapsing under its own weight. At human proportions, let’s say a BMI of 20 for simplicity’s sake, it would have a height of approximately 139,642 meters, aka about 140 kilometers or 87 miles. This is far taller than any mountain and would put it above the Kármán line, the conventionally agreed upon edge of space.
Awesome. For your efforts, I will now tell you the story of why I was afraid of the Wampas Cat for years.
When we were little, any strange sound we heard out in the woods or just pretty much any sound we could hear but not identify, my dad would act all guarded and suspicious and say “I hope that’s not a Wampas Cat, actually I think it is” “don’t go over there or you’ll get got by the Wampas Cat” to me and my brother. It took a few years for us to realize that the Wampas Cat wasn’t real and it was just a play on Cattywampas.
With a population of 8 billion, that makes a cube 2,000 people on each side.
But that would have a lot of empty space between people, so let us just say it would be 1,000 times as big in height, depth and width.
Depends on how thin you slice them.
I remember seeing something that said if you piled up every human into one big pile, it wouldn’t even be a fraction of the size of Los Angeles county and you would barely even notice the pile from space.
