Has a asteroid ever HIT earth?

Just a few million times, over some 4+ billion years.

And there are these craters too.

Yes. Asteroids formed the Earth over 5 Billion years ago. Asteroids hit Earth all the time.
Small ones. Go to Arizona and look at the Crater. Asteroid killed the dinosaurs.

Over the course of Earth's history, many asteroids have hit the planet.

Yes. I've attached a link with some interesting info.

yes, an asteroid collision is most likely what caused the extinction of the Dinosaurs

Of course. There are more than 80 large impact craters known on Earth's surface; here's the Berringer Meteor Crater in Arizona: https://upload.wikimedia.org/wikipedia/commons/4/46/Meteorcrater.jpg

Earth has probably been struck millions of times in the past; but our planet has a dynamic surface, which erases the impact craters over time.

Yes, all the time ever since the formation of the planet.

Yes, asteroids have hit Earth many times. The Moon may exist because of a Mars size planet named Theia impacting Earth at glancing angle. There's the 10 kilometer 6 mile asteroid that impacted the Yucatan. The bus sized Chelyabinsk Russia bolide was small in comparison. And what about the iron nickel meteorite at Mecca?

Yes, many have hit the Earth in the history of the planet.

Probably 1000s if not millions of times

Click on any one on the list.

The Barringer crater is probably the one that looks most like what a non-astronomer expects to see.

For many of them, you can only be sure after doing geological tests in the area. For example:
https://en.wikipedia.org/wiki/Manicouagan_Reservoir

Yes, many times over the History of the Earth and everything else in the Solar System
You only have to look at the Craters
The only uncratered parts are where there has been some Natural re surfacing
With Earth it is its Tectonic Plates that move
Subduction recycles the Surface and Mid Ocean Ridges pushes up new Surface
The most recognisable Crater on Earth is the Barringer Crater in the Arizona Desert, 50, 000 years old
Older Craters have been mostly Eroded and are a mere shadow of themselves
The Chixulub Impact, 65 Million years ago, created the Gulf of Mexico
Its remnants were only found by deep Sonar Prospecting
Lately Russia has been hit twice and Africa once by Airbursts
Which are smaller Asteroids falling through our Atmosphere and blowing up
By far the biggest impact in the history of Earth would have been the Mars sized Proto Planet Theia
The Ejecta that was put in Orbit became Or Moon
Are the signs of that Impact really gone ?
The Pacific Ring of Fire is a Massive Subduction Zone, and about the size of Mars

depends on how you define the term "asteroid".

from the below, asteroids have a diameter of 1 meter or more. There have been many many cases of asteroids that size hitting earth. See reference for a list of major ones. But a 1 m asteroid is not a big deal, it can burn up in the atmosphere.



Definition (Wikipedia): Asteroids are minor planets, especially of the inner Solar System. This has historically been applied to any astronomical object orbiting the Sun that did not resemble a planet-like disc and was not observed to have characteristics of an active comet such as a tail.

There exist millions of asteroids, many thought to be the shattered remnants of planetesimals, bodies within the young Sun's solar nebula that never grew large enough to become planets.

The difference between asteroids and meteoroids is mainly one of size: meteoroids have a diameter of one meter or less, whereas asteroids have a diameter of greater than one meter.

I'm sure it has happened thousands, if not millions of times, throughout history.

yes.................
its name is............Donald Trump

Yes. To your credit they obviously have failed to hit hard enough.

Yes, it has happened,one might have hit the Earth and cause the environmental conditions that destroyed the dinosaurs.

Many times..........

Back when in was about 3 or so, my family and I were out for a walk around our neighborhood and in the sky probably about a mile away we saw an asteroid or something fall through the sky. I'm unaware of it hit but it was still a cool experience.

Of course, the only question to ask at this point is the sharpening of criteria. How MANY times, and how LARGE the asteroid.

Shooooooting stars yeh

Sure. https://en.wikipedia.org/wiki/Theia_(planet)

Yes.
Look up the Tanguska asteroid.
It landed in a remote area of Russia in the early 1900's and did as much damage as an atomic bomb blast could do.

Yes, a great many. Actually happens on a daily basis, most too small to be significant. Some the size of a pea,,some a baseball that càn do damage.
Larger yet, serious problems, up to global.

Only a few years or so ago a small asteroid exploded over Russia with the force of about 30 Hiroshima bombs. A large number of pieces reached the ground. The meteorite crater in Arizona is evidence of a large object hitting the ground.

probably the Moon is a piece of earth from some great collision
