It means that if there is life out there...if...they would be in the present time. the same time as earth. It's just that the universe is so huge it takes light a long time to travel between planets and stars. So lets say A person from earth looks at a star in the sky that isn't really a star, its a planet. On this planet that the person from earth is looking at is an 'alien' who is similarily looking at which he beleives is a star in the sky, but it is really earth. Basically they are both looking at eachothers planets. The light from the stars they are looking at could be anywhere from 10 to thousands of years old because light travels so far between these planets which are billions of miles away. So both the planets (the human and the alien) are both in present time, but the light they see coming from the planet they are looking at is really from the fpast.
