We (or they) can see (many) other solar systems being formed now. Also: the physics allow only certain events to have occurred - from those possibilities they build models and make "theories" (actually hypotheses).

Scientists believe that galaxies formed earlier in the universe's history, with the most distant galaxies being some of the first to have formed after the Big Bang. Studying these distant galaxies can provide insights into the early stages of galaxy formation and evolution.
Scientists hypothesize that the sun formed from a massive cloud of gas and dust known as a solar nebula. This cloud collapsed under its own gravity, leading to the formation of the sun at the center of the solar system.
From eye-witness testimony...they are History.
Relative dating methods help scientists determine the sequence of events in Earth's history by comparing the ages of rock layers and fossils. This allows them to establish a timeline of when different events occurred without assigning specific numerical ages. This is important for understanding the order of events and the evolution of life on Earth.
Scientists hypothesize that chemical events preceded the origin of life on Earth because organic molecules, essential for life, can be formed through non-biological processes like chemical reactions and catalysis. Studying these chemical events can provide insights into how the building blocks of life may have formed on early Earth before biological processes took over.

The Royal Society of London was formed to encourage scientists to share experimental data.
Scientists think that Barbados was formed about almost a million years ago.
The rock band We are Scientists were formed in the year 2000. They have so far released four studio albums with their most recent album Barbara in 2010.
