Dropping a line to aliens out there

Hello, out there! Earth here, how'd you be? Just dropping a line to tell you about us earthlings, I guess that's what you'd call us, if your telescope things could see us standing here looking up at you. We're the Blue Planet, one of eight, orbiting our yellow-dwarf star in the milky way, sending all sorts of electronic beams out that you can probably hear and get annoyed by. Our Plant Water, which it should be called, is covered in blue watery seas and white clouds with brown land masses in between, dotted with green forests of trees, crops and grey cities, farms and houses that we've built for habitation. Our life form is based on carbon and water, and is called organic. I'm not sure if that's your stuff as well, but never mind, it matters little provided, we can see, hear, feel and communicate with each other. Not sure if you got the Gold Disk we sent to you previously packed with music, poems, pictures and all sorts of emotional, heart-felt tomes, and mathematical, images and thinking stuff, but if you missed it, I'll try to summarize it thus: We are bipeds with two arms and legs. We have two sexes male and female, we call them, there may be in betweens as well. We live for about 100 of our earth years, We pair-up as couples, breed and have two to four babies during our lifetimes. This keeps our populations going through the generations since our species arose about 300,000 earth years ago. In some ways we've been too successful and we have overpopulated our planet, and caused much devastation to our environment and to the other living things here. We mostly love, sing, laugh and enjoy being here, and get along pretty well, but like most folks I guess, we fight and kill each other too, mostly for beliefs and kinships, and squabbles, about scarce resources, religions, races, hates, and political beliefs, that lead to fighting and wars, that never seem to end. Peace is so hard to find, especially lately. But we reach out to others when we can and try to make friends and have fun. But beware my alien friends: If you ever come this way for a visit we're likely to blow you outta the sky first and foremost, and leave the questions of why and what-fors, for later. Another thing I should mention in closing: We may not be still here when you come. The key is under the doormat.
