Why can't evolution occur in 5-50,000 years? Why millions

Evolution is constantly occurring. The amount of years isn't as important as the number of generations.

Evolution can happen in a lab so it doesn't exactly take millions of years. Just look at antibiotic resistance, pretty recent phenomenon and the result of evolution.

People who deny evolution needn't take yearly flu jabs when they get old ^^ They got nothing to worry about.

Because a set of genes needs to basically be wiped from the planet and be replaced by some others, so an entire animal population cycle must first go

This is not real. The earth was created in 7 days by our father, the Lord. Evolution does not exist. You have sinned against the Holy Spirit.

The who and the what?

Of course he is! considering he's a miserable ******* who likes to make others life a misery to "test them". Sounds just like the British government, testing to see just how much they can push us.

The short answer is that it does.

Evolution is a scale - species are evolving all the time. It took 4 billion years to go from single cells to humans, whereas types of fly can split into two different species in a matter of 100 generations (for a fly, not very long).

Evolution is a slow and gradual process (although admittedly some of it happens faster than we once thought). This is why it is hard for us to get our heads - which live for 80 odd years around it - best bet is to read a biology book. I recommend "The Ancestor's Tale" by Richard Dawkins, it's fascinating

Micro scale evolutionary changes can happen in just a single mutation, but large scale changes require many generations and mutations, along with existential pressures, to manifest themselves in a species. Just look up an account online, there are plenty of helpful examples.

Also, here is a really useful cartoon giving a general overview;

Well its usually because evolution is largely driven by environmental changes over time that introduce selection pressures that weed out inferior forms, favouring those with genes that produce physical characteristics that help them survive in that environment to produce offspring in future. These kinds of changes take millions of years because it doesnt all happen in one go, its kind of a filtering effect when you think about it. Evolution is to put simply the most elegant and time dependent form of metamorphosis there is in organic, biologically active beings today.
