how do i git out

Credits can be earned from using turns, from selling things on the market, from slave empires, and from artifacts. The most common ways of earning money are turns and the market. As a Terran, you will generally use either Commercial or Agriculture as your main form of income. Commercial provides a stable income that you can see immediately, while with Agriculture you will usually have a negative credit income and make your money by selling food. For beginning, I`d reccomend Commercial. Research Commercial Infrastructure, to level 20, then research ships and clusters from the Research Tree. After you`ve done this, you will want to get more planets. That can be done by either exploring or attacking. Make sure to build just enough housing on your planets to get a population equal to or within 10 above the total land of the planet, and assign all the rest of the land to Commercial.

First, read the manual and the walkthrough.

If you are terran, I`d suggest you to research and build agriculture if you want lots of money after selling the produced food on the market, or research and build commercial for an easier way to get money.

After you get a few millions you can do "strip mining", in which you explore for planets with a lot of Ore, extract that ore and sell on the market for 10,000 a piece. You can get millions in no time.

After you get like 500 millions by strip mining, you can explore for high land planets and stick to agriculture / commercial again.
