Hello and welcome.
Before you run away...please remember something I told my children. I said, "If the other children are joking with you, it means they like you. The time to worry is when the other children ignore you." We are a friendly bunch here on NGA and sometimes we get carried away, especially after working in the blazing sun all day.
@vee333, I am sorry to see you have received flippant answers to your serious question (it just means we like you!!). Since I don't know how large your vegetable garden is, the best serious advice I can offer is to break the garden into sections and plant one section each day. Some things like tomatoes are planted once and will grow and produce all season (in most climates). Other veggies, such as beans, need to be planted every 2 weeks to assure a continuous supply.
Planting seeds can be somewhat backbreaking especially as we get older. If you have something to sit on it makes the job easier.
Mixing small seeds with sand sometimes helps. I use a piece of lumber to make a 'dent' in the garden soil, then sprinkle the seed/sand mixture into the dent. I cover the seeds with either very light, sifted soil or sometimes with a mixture of sifted peat moss and vermiculite. That helps to mark the row. I also put a few radish seeds into the mix. The radishes germinate quickly so I know exactly where the row is and can do my weeding.
I am handicapped so I use all raised beds to make it a bit easier on my back and legs. This is one raised bed planted with rape/canola seeds using the piece of lumber to make a straight planting row.
Look online in a Google Image search for a "multi dibble board". Using a board makes it very easy to plant things like carrots, spinach, lettuce, etc. You can DIY a few different dibble boards with the pegs set for each type of seed.
Others may be along with helpful answers soon...although I really did like the shotgun idea.
