In conclusion, Harun Yahya is an idiot and/or a liar.
I'm leaning towards idiot.
Yeah, me too. Practically everything in the entire video is nothing but bullshit. Are there asteroids orbiting Earth? Yes, but no where near the numbers this moron says there are. It is speculated that there may be as many as 18000 "mini-moons" that have been captured by Earth's gravity, but they are very small. There are even some that are captured, orbit the planet for a while, and then are lost to space again or enter our atmosphere and burn up. Very few of them are large enough to even be noticed if they fall to earth, much less do much, if any damage, if they should reach the ground. Of the thousands of rocks orbiting Earth now, it is estimated that only 1 or 2 are washing machine sized and only a thousand or so are the size of a softball. Not much of a threat to mankind, I'd say. Earth's gravity simply isn't strong enough to capture anything much larger.
Where the real danger lies is in what are called Near Earth Objects (NEOs.) These are asteroids that actually cross or come near to Earth's orbit and have the potential to strike our planet. There are currently several thousand NEOs being tracked. There has recently been a subset of NEOs that have been classified as PHAs (Potentially Hazardous Asteroids.) There are approximately 4700 of these objects with an estimated diameter of 330 feet or more, large enough to do substantial damage. We've had a few near misses over the past few years and, in fact, had one large enough to cause considerable damage had it struck Earth that crossed our path about six months ago
within the orbit of the moon.
It is true that surveys have found more and more of these asteroids over the course of the past 30 years or so. But that is not a result of them "massing around Earth." It is simply a matter of surveillance equipment improving to the point of being able to find them. It isn't easy to spot a small unlit object floating around in space. Only more advance observing methods and equipment has enabled astronomers to find them in recent years.
