How are humans on earth now when dinosaurs lived long ago?

Answer 1

It has always been suggested that a world-wide disaster killed off the dinosaurs, such as a meteor impact, which can be proven. Not ALL life became extinct though. Almost all sea-based creatures retained their life and were able to carry on as usual, it was the land-based creatures that suffered the direct consequences of the impact. This was 60,000,000 years ago, and of course humans were not evolved yet. If we talk of evolution we can say that the evolution from apes was a long way off, and not ALL animals died. Of course at this time monkeys were not around either, and so they obviously evolved from something else. A lot happens in 60,000,000 years, such as widespread evolution, and of course more species were being formed on the world. Look at crocodiles, for example. Water-based animals that are said to have been around the time your average dino walked on the earth. We can tell that they are of the same group by their specific characteristics, such as their tough armoured skin, which most dinosaurs had which enabled them to survive when living in the wild, as well as to fight off any predators they may have encountered. To really answer your question, the disaster wiped out most species of dinosaurs, but some certain species, such as many that had to ability to fly or swim, escaped relatively unharmed. 60m years allowed for mass evolution, as this is a long time period, and so humans were not even around at this time, and simply evolved from a closest ancestor - the monkey/ape.
