Is there a theory to show the vertical axis of earth relocated by same rock that hit it 60 million years ago?

Planet earth climate used to be similar to what we experience today along equator and is known as equatorial or tropical climate with little change in temperature all year round. Up until 60 million years ago there was no need for warm blooded animals such as mammals to exist. Warm blooded species are easily adaptable to climate and temperature changes. In contrast cold blooded animals are far less adaptable creatures. They die or begin a pive life by a sudden fall in temperature. Today the major part of cold blooded animals live in water which not only reacts slower than air to sudden temperature changes but also provides boundless and vast territories, make it easier to move and transport to different parts without facing land problems. If this theory stands, then it was mainly the freezing cold winters and boiling hot summers afterwards that made dinosaurs vanished (or evolved) and not the popular theory which blames the direct effects of that big explosion 60,000,000 years ago.
