@YesuWangu I'm still not sure whether I understand what you are saying. Is it that you do not believe meteorites, meteors, asteriods and comets exist, or that this particular one in Kenya is not a meteorite?
Meteorites exist and constantly fall to Earth. Many are not large enough to be observed and their impact sites located. Meteorites that leave behind craters are larger and rarer, that's why physical signs of impact may not be immediately visible at sites of smaller meteorite impacts.
The other heavenly bodies mentioned above are all observable.
Although you do not want to be referred to other sources if you want to see actual physical damage caused by large meteorites, have a look at the devastation caused by an exploding meteorite over Tunguska in Russia or any craters.
In a place where thought is abandoned, freedom can become a curse.
