The image shows very young seedlings emerging from the soil. They feature smooth, oval to oblong cotyledons (seed leaves) on slender green stems, which are typical early developmental stages for vines in the gourd family.

Light
Full sun, requiring at least 6 to 8 hours of direct sunlight daily.
Water
Requires moderate and consistent moisture, especially during germination and early growth. Keep the soil evenly moist but not waterlogged. Avoid overhead watering to prevent moisture-related foliage issues.
Growth
Sprawling annual vine with a rapid growth rate, producing long, trailing stems that can spread up to several feet across the ground or climb with support structures.

Care instructions

Provide full sun and consistently moist, well-draining soil rich in organic matter. Water at the base regularly, allowing the top inch of soil to dry out between waterings. Apply a balanced fertilizer during the growing season to support vigorous vine development.

Watering

Requires moderate and consistent moisture, especially during germination and early growth. Keep the soil evenly moist but not waterlogged. Avoid overhead watering to prevent moisture-related foliage issues.

Similar species

Other members of the Cucurbitaceae family, such as cantaloupe or squash seedlings, which also exhibit similar oval cotyledons at the earliest germination stage.

Looks like it could be a watermelon. I did plant watermelon seeds there.
