In the field of Astrobiology, the precise location, prevalence and age ofpotential extraterrestrial intelligence (ETI) have not been explicitlyexplored. Here, we address these inquiries using an empirical galacticsimulation model to analyze the spatial-temporal variations and the prevalenceof potential ETI within the Galaxy. This model estimates the occurrence of ETI,providing guidance on where to look for intelligent life in the Search for ETI(SETI) with a set of criteria, including well-established astrophysicalproperties of the Milky Way. Further, typically overlooked factors such as theprocess of abiogenesis, different evolutionary timescales and potentialself-annihilation are incorporated to explore the growth propensity of ETI. Weexamine three major parameters: 1) the likelihood rate of abiogenesis({\lambda}A); 2) evolutionary timescales (Tevo); and 3) probability ofself-annihilation of complex life (Pann). We found Pann to be the mostinfluential parameter determining the quantity and age of galactic intelligentlife. Our model simulation also identified a peak location for ETI at anannular region approximately 4 kpc from the Galactic center around 8 billionyears (Gyrs), with complex life decreasing temporally and spatially from thepeak point, asserting a high likelihood of intelligent life in the galacticinner disk. The simulated age distributions also suggest that most of theintelligent life in our galaxy are young, thus making observation or detectiondifficult.
