No. I answered this on the 'did we land on the moon thread': We didn't descend form modern monkeys. Modern monkeys and modern humans descended from a common ancestor. Here's an analaogy to answer the quesion:
My father’s father died many years ago, but he left quite a few living descendants, including me, my sister, and my paternal cousins. To ask the question ‘If humans evolved from monkeys, how come there are still monkeys?’ is a bit like asking me ‘If you are descended from your grandfather, how come your cousins are still alive?’ The question doesn’t make any sense: why shouldn’t my cousins still be alive?.


Why are monkeys always brought up in these arguments? Evolution doesn't just mean that humans are descended from monkey-like creatures. If you go (a lot) further back we are descended from fish, too. If you go far enough back, all life on earth is descended from single-celled organisms.
Also if you agree that 'Living things were evolving to adapt to their environment', then you agree with the theory of evolution. That's all it is, evolving to be a better fit to current environment. The problem people have is timescales. We didn't descend from monkeys overnight, it happened over millions of years.


Yes, see above.
