If you planted each seed spaced well away from the others, you won't need to thin your plants until you're ready to transplant them. They will be fine if you can fit your finger between each seedling. If you broadcast lots of seeds and the seedlings are crowded you should thin them out by cutting or snipping off the extra plants with scissors. It's difficult to pull them out - doing so will damage the roots of the plants you want to save. Snipping the stems at soil level will destroy the plants without harming the ones you want to keep. The first leaves to emerge are called seed leaves and they are oval/round. These are not true leaves. The seed leaves (called cotyledons) will die off after they've provided their nutrients to the plant. The next set of leaves will emerge looking very much like tomato plant leaves and are these are called true leaves. Hope this clarifies things for you.
