They were erected around the coast, looking at the sea. Probably they were put there as some sort of protection from invaders from the sea (real or imagined), so the would-be invaders would look at the figures and probably mistake them for giants from afar. I'm just speculating, btw, probably we will never know for sure, because the culture who made them disappeared completely.

I observed Will-o-the wisps when I was 7 years old. In Australia, we call them "Min Min Lights". Father took us out in the car in the middle of the night, and we watched them bouncing all over the fields. What I noted was that if I looked at one directly, that particular light would always appear right in front of my gaze, and would change color. It's the same gradual color change you get if you look at a bright light, and the after image fades off, changing colors as it does so. Old timers out bush used to say they were caused by vapours released from the artesian bores (boiling hot mineral water sources). However, the Artesian Basin (which underlies most of western Queensland where I was living at the time) is always there, but the "min min lights" weren't always present, so I've never really known their origin. But I did figure out how someone could chase one and fall over a cliff. It's because that ONE you look at long enough, imprints like a negative after-image of a flash light...so it's always right where you look. As soon as I figured out that directly gazing caused that effect, then I experimented by not looking directly at them, but out of the corner of my eye (kind of glazing over and looking past them). That way I could see dozens of them, all bouncing like helium filled balloons, and all different colors. An amazing, not to be forgotten experience. It terrified my younger brother though...

You can actually hear earthquake before it arrives.. During 2015 a 7.8 magnitude earthquake shook Nepal followed by a 7.3 the very next day. Couple weeks later one morning at 7am local time while I was scrolling facebook, I heard birds going crazy and within seconds I started hearing a deep humming sound that started getting louder and louder and within seconds of that everything started shaking. Later found out it was an aftershock of around magnitude 4.5ish.

[@swordzanderson5352]

Technically, the earthquake happened before the noise. What you're hearing is the shockwave of sound that travels faster, obviously, than the shockwave in the earth that caused the 4.5 magnitude aftershock

[@blahfasel2000]

​@@swordzanderson5352 Seismic waves travel at 6 times the speed of sound in air or more. Also even the strongest earthquakes don't create an athmospheric shock wave. Instead what was most likely happening was that they were hearing secondary sounds created by the P-waves (pressure waves) of the earthquake coming through which travel about 70% faster than the S-waves (shear waves). S-waves are the ones that cause most of the destruction and can be felt more strongly. This speed difference is also what earthquake warning systems rely on, giving a few minutes (depending on distance to the epicenter) of warning before the destructive S-waves hit.

Vultures fly very high, and in general, don't empty their whole-ass stomach contents all in one go while they are airborne.

That line is based how conspiracy theorists say the government cover ups for UFOs always include stuff like swamp gas or light from stars or planets tricking the eye. It also mocks how the official report for the Roswell incident was a weather balloon. The funny thing is the Roswell weather balloon was real and contained atmospheric testers used to detect nuclear explosions hence the Top Secret nature of it, and many UFOs are in fact sighted over swamps so swamp gas is a potential cause.

[@madnessbydesignVria]

@@hmnhntr No, they're not based on observable or confirmed phenomena. Look at the Easter Island 'Hats' story. There is literally no evidence to suggest how it was done at all. THAT'S the mystery. "Well, they must have built a ramp, and had 2-3 guys pulling ropes from on top of the head.", was the answer. "Case closed.", said they. Now turn your brain on, and think for a moment. These statues are about 30 feet tall (10 meters). The 'hats' weighed about 12 metric tons. That's over 26,000 pounds each. Dirt ramps would compress heavily. So, 15 guys are able to pull 2 metric tons/over 26,000 lbs (meaning each man is able to pull over 1,733 pounds) UP a soft ramp (no traction, and the ramp's compression makes the work way harder) - and then, turn these rock behemoths 90 degrees (to make them sit flat on the 'heads'? I'd love to see that. Is there video of the "Scientists" testing this theory? (Spoiler) There is not. The 'ramp' would have to be a 'mound' encircling the entire statue to give 15 men a place to stand for this to work (the statue head is only about 6' across). Put your computer models to the test before claiming victory. Now consider, there are over a thousand of these statues. Yeah. The sheer volume of material needed to make that many ramps would take decades (probably longer) to accumulate, utilize, disassemble, and move to the next statue, and that's assuming the entire population of the island had nothing better to do. It's a dumb theory - and there is NO evidence to support it (no huge pits where all this material came from, no piles from where it was left when they were done, etc. - you know, 'evidence'). It's just someone's best guess. Not having a better idea doesn't count as evidence. So, that's why I wrote that it doesn't make sense at all. I can break down the others as well, if you like (since there are glaring problems with each story), but this one can serve as a template. Simple Logic says none of these cases are closed at all. Saying it's been solved shuts down real Science from trying to find real answers. They're all just guesses (and frankly, not good ones). There's nothing wrong with a mystery - until you rubber stamp a bs answer on it and call it a day...
