Science knows nothing with 100% accuracy and only arrogant ignoramuses are that certain. We are within 1% +/- on the age of the earth and from converging lines of many evidences. Science uses probability statements on such concepts and theories and there is always more to know about something and theory is often modified and even overthrown. Science is not religion, thankfully, so evidence is used in support of positions and some of those positions are very certain. How the earth was formed, and we see stellar nurseries in action, and how old the earth is, and we have many lines of evidence there, is very certain.
These evidences are easy to Google.

70%
Obviously trees occupy the 10 percent of earth but it's not correct as a earth surface measurement metric unit. Water occupies the 71 percent and land the 29 percent.
One possible person is Eratosthenes of Cyrene ~230 BC as he was a Greek scientist who calculated the circumference of the Earth, with remarkable accuracy (some values for the "stadia" he used gives a result within 6% of the actual polar circumference). See link for further information
It's about 25-30 percent land.
70 percent of Earth is mostly covered in water
Yes it is.
When calculated according to the 4.6 billion years since earth was formed humans have live in it 0.09 percent of the time.
100 percent of possibility there is a life in cosmos like earth.
No. Less thsan one percent of the Sun's total energy falls anywhere near Earth.
Life formed on earth because the conditions were right for life to begin and evolve. While some think that life (as we know it) is only possible on our earth, others think that somewhere, in the vastness of the Universe, life on a similar planet to earth must exist.
It is not possible to make Earth by combining moons. The Earth formed from the accretion of various materials during the early solar system's formation.
it is formed 2 miles away from the earth
Earth's moon ... the one you see in the sky from your backyard ... does not circle Mars.The distance from earth to our moon is less than 1/2 percent of the closest possible distance from earth to Mars.
Yes, sedimentary rocks do cover about 75 percent of the Earth's surface. These rocks are formed from the accumulation and solidification of sediment, such as sand, mud, and organic material, over time. They make up the majority of the Earth's crust and are found in layers all around the world.
A landform is naturally formed feature on earth's surface.
The earth's atmosphere is very old. It was formed when earth was formed.
I'd say with 100% accuracy that all humans were born here on earth.
