I assume you mean "why is it perfect for supporting life?" There are two answers. The scientific answer is that the Earth just happens to be the right size, have the right combination of elements, and be the perfect distance from its star (Sol, the Sun) to allow it to have the liquid water, breathable atmosphere and moderate temperatures necessary for life as we know it. Other planets in our solar system are either too near or too far from the Sun (and so are too hot or too cold to support life). Some also lack the right combination of elements or are too dense (too high gravity). There may very well be (and probably are many) other planets in other star systems that are also just the right size, have the right elements, and are the right distance from their stars to support life. The religious answer is that God specifically designed the Earth to support the life he created on it. One can accept either of these answers, or both of them, depending upon one's personal beliefs.
Earth is not perfectly sphere, the Earth bulges at its equator for it is spinning very fast on its axis.
For Earth to become a perfect shape, it would need to be perfectly spherical. This would require it to have a uniform distribution of mass and no geographical features like mountains or valleys. Achieving a perfectly spherical shape would mean Earth would have to be completely smooth and free of any irregularities.
Earth's rotation causes the planet to warp slightly, which makes it slightly oblong instead of being a perfect sphere.
Earth's shape is an oblate spheroid, meaning it is nearly spherical but slightly flattened at the poles and bulging at the equator. The difference between the polar and equatorial diameters is about 42.75 kilometers, making Earth's shape very close to a perfect sphere.
To make the Earth a perfect sphere, all landmasses would need to be flattened to the same elevation as the ocean floors. This would require significant redistributions of mass across the planet. Additionally, Earth's rotation would need to be perfectly uniform to maintain the spherical shape.
so that we don't slip ......................... i know it is not true
no because no one is perfect. there is always a way to improve the earth
The seven perfects of Earth are Perfect Faith, Perfect Love, Perfect Charity, Perfect Honesty, Perfect Unselfishness, Perfect Wisdom, and Perfect Courage. These qualities are considered virtues that help individuals lead fulfilling and righteous lives.
Luck. I'm sure there are plenty of other "perfect" planets out there, it just so happens we live on this one. The mass of the planet and the speed it orbits the sun at keep it at a perfect distance away.
The Earth is not a perfect sphere, so the distance to the center of the Earth varies from 6378 km (3963 miles) at the equator to 6357 km (3950 miles) at the poles.

Nobody is perfect on earth
Because it is the perfect length away from the sun so it will not burn through the atmosphere
Earth has atmosphere. It helps in maintaining a perfect temperature to live.
In perfect and complete synchrony.

It is Perfect, so It has to be Perfect for you!
