then who is to blame millions of years ago? This makes no sense to me what so ever.

In the past it was all natural cycles which happen very slowly over thousands of years but now because of all the greenhouse gases it's happening much faster.

Variations in Earth's orbit, Tectonic plate activity, increases in solar activity, and major volcanic eruptions have all played a fairly prominent role in shaping the history of Earth's climate. All of these events were perfectly natural and had nothing to do with us humans at all.
However, the warming we are currently experiencing is much, much More rapid than anything experienced in all of human history, and is heavily affected by our activity.
So while it's somewhat difficult to pin down the exact cause of many past climate changes, the cause of the current change is well documented and understood by science.

dinosaurs were way out of line with there pollution and poisonous gases and SUVS so the earth took care of them and wiped them off first the big ones and then the small ones. the earth is just renewing its self every few hundred thousand years at least what it can control, how soon will it be until earth is tired of cleaning up after us and just wipe us out. i know it sounds like madness but look at it form the earths point of view

The global warming is really the evolution of the earth but the pollution from humans is just speeding the process.

There are tons of changes caused by nature, those cannot be changed. But the things that we do especially at the mass scale at which we do it and in terms that they are avoidable or mitigatible and manageable, yet we are doing little to fix it.
Putting your hands over your ears and saying nyyyh, nyyyyh, nyyyh doesnt stop the truth, whether you want to hear it or not.

What can change the ozone layer? Man made chemicals can. Chemicals released from erupting volcanoes can. Both can happen in our time, and volcanoes erupted in the past.
Do some research about what can cause ozone erosion before freaking out and making baseless assumptions.
