Most likely location for life in a galaxy

The evolution of complex life is time consuming and requires the availability of the right chemicals.

Any other systems that evolved from say the same gas cloud may be more likely to have the same mix, also distance from the galactic core is likely better.

Near the core there will be more background radiation from everywhere and probably more debris swirling around which could result in more impacts and disruptions to the environment.

So looking for similar big picture conditions would be useful.
