We will begin with a brief introduction to the Amplitude Bootstrap in Minkowski space. Then, we will use the same idea to bootstrap amplitudes in (A)dS space by introducing a new representation of on-shell AdS amplitudes in Mellin Momentum space. We will also explain the connection between this amplitude and Cosmological correlators, which is the main motivation of this study. Specifically, we will illustrate how the understanding of pole structure will completely fix the spin-1 exchange amplitude. Finally, we will use the double copy to construct the four-graviton amplitude in AdS_{d+1}.
