The earth is around 4.5 billion years old. Human-like animals have been around for about 6 million years, but modern humans only showed up about 200,000 years ago. You can see, this is a very short part of the total lifespan of the planet.
Humans have existed for only about 0.2% of Earth's history, which is approximately 200,000 years out of Earth's 4.5 billion-year history. This indicates that humans are a relatively recent addition to the planet.
The modern form of humans (i.e. homo sapiens sapiens) evolved about 200,000 years ago.
Yes, Cro-Magnon humans lived during the Upper Paleolithic period, around 40,000 to 10,000 years ago. Pangaea, the supercontinent, existed about 335 to 175 million years ago, long before the time of Cro-Magnons.
Cavemen existed during the Paleolithic period, which began around 2.6 million years ago and ended around 10,000 years ago. They lived during the Stone Age, using basic stone tools and leading a hunter-gatherer lifestyle.
Cro-Magnon humans existed around 40,000 to 10,000 years ago during the Upper Paleolithic period. They were early modern humans that lived across Europe, exhibiting advanced tool-making skills and artistic abilities.
Snails and slugs are mollusks. Humans and mollusks have co-existed since humans emerged, and I would imagine humans have always been aware of the existence of mollusks. We're kind of smart like that.
That depends on how long ago humans developed. Assume 100,000 years, the earth is about 4,000,000,000 years old. So% = 100,000 / 4,000,000,000 x 100 = 0.0025 %

No. Humans are a relatively recent evolution.
By slowing down the earths rotation but will not make effect to humans .

No. Pangaea is thought to have broken up about 240 million years ago during the Triassic Period, while early man only evolved during the last few million years.
