Both "conservative" and "progressive" ideologies generally allow for change, but in different ways.
I don't subscribe to conservative ideology myself, but traditional conservatism is an understandable outlook.
It's also a far too simplistic way of looking at politics: usually groups will be in favour of same changes and opposed to others, regardless of what they call themselves.
There are also issues where it's not even clear what a "conservative" approach would be. Should action be taken against global warming, to prevent potentially undesirable climate change, or resist taking action, to prevent changes to the economic status quo? For some reason, modern conservatives generally seem to prefer the latter.
In practice, the fundamental difference is probably more about a person's radius of empathy (progressives tend to apply their empathy to a larger group of people), and then lots of vaguely related things flow from that, e.g. different outlooks on power (conservatives prefer a strong man - obviously only assuming he's from their own "tribe" - and therefore strongly tend towards authoritarianism) and economics (empathy with more people tends to make one prefer more equal distributions of wealth and income).
The terms progressive and conservative simply arose at a time when the world was largely shaped the way conservatives like. Since then, the world has changed more towards the progressive vision, so today conservatives do want to change creating things.
