Plot of measured distance to distant galaxies mapped in all direction in the sky, against their measured velocity as they move away from us, shows vast majority of them would be on top of us 13.7 billion years ago.
It is a good bet the universe in anyway similar to ours and able to form stars and planets begun around 13.7 billion years ago.
